Effect of EDTA on Tomatoes Plants Seedlings Under Nickel Toxicity

CHAPTER ONE1.0 INTRODUCTION 1.1     NICKEL1.1.1  Occurrence         Nickel (Ni) is a metallic element,with atomic number 28; atomic weight 58.69. Is a metal, which belongs to group VIIIB of the periodic table. The most important oxidation state of nickel is +2, although the +3 and +4 oxidation states are also known (Tundermann et al., 2005). Nickel resembles iron, cobalt, and copper in its chemical properties. However, unlike cobalt and iron, ...

THE MECHANOCHEMICAL AND SOLVENT – BASED SYNTHESIS AND CHARACTERIZATION OF 3,4,5-TRIHYDROXYLBENZOIC ACID CU(II) COMPLEXES.

Mechanochemical synthesis of  [Cu(OOCCH3)2(THB)2] and the Mechanochemical synthesis of  [Cu(OOCCH3)2(THB)2] were carried out, and a  brown solid complexes obtained in both experiment was washed in ethanol respectively. The  physical and instrumental characterisation of the complexes carried out revealed that the complexes obtained are the same

Quantitative Analysis of Carotene and Ascorbic acid from Carrot, Cucumber, Eggplant and Tomatoes

ABSTRACTSpectroscopic method was used to determine quantities of carotene and ascorbic acid in carrot, cucumber, eggplant and tomatoes. The result shows that carrot has higher concentration of carotene =0.1430, follow by eggplant = 0.6950 and tomatoes = 0.0368 and cucumber has the least concentration of carotene =0.0139. The result also show carrot has higher concentration of ascorbic acid 0.958×10-4 mol/d3 follow by tomatoes 0.944×10-4 mol/d3 and eggplant 0.943×10-4 mol/d3 cucumber 0.90...

POLLUTION INDICES OF TRACE METALS IN ROADSIDE SOIL

ABSTRACT   Roadside soil samples were obtained from Eka Street, Oron Road, Ikot Ekpene Road and Nwaniba Road within Uyo metropolis, Akwa Ibom State. Roadside soils were also obtained from Uwana Lane and used as Control. These samples and Control were analysed for the concentration of Cadmium (Cd), Nickel (Ni), Lead (Pb), Zinc (Zn) and Iron using Atomic Absorption Spectrophotometer (AAS) unicam 939 model. Results obtained indicated the following mean concentration (mg/kg) for ...

In Vitro Evaluation of Metal Chelating and Ferric Reducing Potentials of Methanol Extracts of Adasonia digitata Leaf

ABSTRACTAdansonia digitata L. (Malvaceae) is commonly known as baobab tree native to Africa. Baobab is a multi-purpose tree which offers protection and provides food, clothing and medicine as well as raw material for many useful items. This study aims to elucidate the metal chelating and ferric reducing potentials of methanol extracts of Adansonia digitata L. (Malvaceae) leaf using in vitro model. Phytochemical screening was carried out on the extract and it showed that the extract ...

COMPARATIVE CHARACTERIZATION OF SOME PORTLAND CEMENTS SOLD IN SOKOTO CITY.

ABSTRACTThe aim of this research was to characterize some Portland cements (Bua, Dangote and Sokoto cement) sold in Sokoto city using standard methods; due to the persistent collapse of buildings. The results showed that Sokoto cement recorded the least CaO content (58.99%) while Dangote cement had the highest CaO content being 61.56%. All the samples have Al2O3, SiO2 and Fe2O3 contents within the acceptable limits with the exception of Dangote with SiO2 content being below the required stand...

Comparative determination of Calcium and Magnesium in food substances using Atomic absorption spectrophotometry and EDTA Titrimetry

A comparative study was carried out for the determination of calcium and magnesium in milk and water melon (food sources of calcium and magnesium). Mixed standard solutions of calcium and magnesium (spike) were added to the samples before digesting with a mixture of concentrated nitric acid and concentrated hydrochloric acid (1:3). The calcium and magnesium content of the digest were determined using flame atomic absorption spectrophotometer (FAAS) and EDTA titration. The percentage re...

BIOETHANOL PRODUCTION FROM GROUNDNUT SHELL (Arachis hypogaea) AND CARPET GRASS (Axonopus flexuosus) BY ACID HYDROLYSIS USING Saccharomyces cerevisiae

ABSTRACTGroundnut (Arachis Hypogaea) shell and carpet grass (Axonopus flexuosus) were assessed for bioethanol production using dilute acid hydrolysis (10 %, 15 % and 20 % H2SO4) and fermentation using yeast (saccharomyces cerevisiae). The percentage yields were determined to be 27.15 %, 19.69 % and 8.79 % for groundnut shell and 22.69 %, 13.92 % and 7.69 % for carpet grass respectively. The densities of the bioethanol produced were calculated to be 0.8072 g/cm3 for groundnut shell and 0.8303 ...

Antifungal Activity of Mimosa Pudica,Isolation and NMR Characterization of Bioactive Components.

ABSTRACT In this study, the whole plant of Mimosa pudica was extracted using absolute ethanol. The crude ethanolic extract and its isolated triterpenoid glycoside were tested for antifungal activity towards Aspergillus flavus and Trichophyton rubrum using Well Diffusion Method. At concentrations of 25 –100 mg/mL, the extract possesses antifungal activity (from being partially active to very active) against Aspergillus flavus and Trichophyton rubrum. The TLC profile of th...

ANALYSIS OF TRACE METALS IN MUSCLE AND LIVER OF COW MEAT PURCHASE FROM URUA IKOT OSURUA

ANALYSIS OF TRACEMETALS IN MUSCLE AND LIVER OF COWMEAT PURCHASE FROM URUA IKOT OSURUA.A RESEARCH PROJECTABSTRACTThe concentration of trace metals (cadmium, Lead, Iron, Copper and Zinc) in two organ (muscle and liver) from cow meat obtained from urua Ikot Osurua was determined using Atomic absorption spectrophotometer. Their result was as follows muscle (Cadmium: 0.78±0.002, Lead: 0.044±0.001, Iron: 0.711±0.000, Copper: 0.833±0.082, Zinc: 0.580±0.001). The obtained result declared that co...

ANALYSIS OF TRACE METALS IN KIDNEY AND SKIN OF COWMEAT PURCHASE FROM URUA MBAKARA   A RESEARCH PROJECT REPORT     ABSTRACT This study was to determine the concentration of trace metal (Cd, Pb, Fe, Cu and Zn) in the skin and kidney of a cowmeat. The analysis was carried out using Atomic Absorption Spectrophotometer (AAS). The concentration of the trace metals in the different organs were as follows, skin cadmium 0.86 + 0.003, Lead 1.09 + 0.002, Iron 14.30 + 0.001...

The Effect of Broken Homes on Science Education Students: A Case Study of Some Selected Secondary Schools in Augie Local Government

INTRODUCTIONThe home is the primary institution for children, home as perceived by Abdulganiyu (1997), Christe (2009), defined home as a place in which an individual or a family can rest and store personal property.Haven’t define the concept of home it is therefore important to define family. The family can therefore, be looked at as a social group characterized by common resident, economic, cooperation and production.When a child is born, the family is the first primary group with which th...
