COMPARATIVE DETERMINATION OF CALCIUM AND MAGNESIUM IN FOOD SUBSTANCES USING EDTA-TITRIMETRY AND FLAME ATOMIC ABSORPTION SPECTROMETRY (FAAS)

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...

COMPARATIVE PHYSICO CHEMICAL ANALYSIS OF UNDERGROUND WATER SOURCE OF TAP AND SOME SELECTED BOREHOLE IN JAKUSKO LOCAL GOVERNMENT, YOBE STATE.

ABSTRACTThis research paper analyses the physical and chemical parameters of water sample collected from Jakusko local government area, Yobe State. It is predicted that the water in this area may be the cause of kidney problem people have been suffering from, this is why we decided to embark on this research work to enable us ascertain wither the water is the main cause of the kidney problem in the area. The water sample collected is from the following areas: mai yandu street, mai anguw...

Laboratory Preparation and Analyses of Ochre Soaps with Characteristic Medicinal Effect on Dermatophylosis

ABSTRACTFour oil namely palm kernel oil, palm oil, ground nut oil and shear butter oil were employedin the production of ochre soap. Dermatophilus congolensis were used as organism to test foranti-bacteria or medicated activities of this soap. The physical properties of the soap samplessuch as colour, texture and foaming were determine. The chemical properties such as acidvalue, percentage free alkalinity, percentage insoluble matter, percentage moisture and pHvalue were determined. It was fo...

STUDIES ON CORROSION INHIBITION POTENTIAL OF INDIGO CARMINE ON MILD STEEL IN ACIDIC MEDIUM

ABSTRACTStudies on corrosion inhibition potential of Indigo Carmine extract on mild steel in acidic medium was carried out using weight loss and electrochemical techniques. It was observed that the Indigo Carmine extract retarded the dissolution of mild steel in the acidic medium. The corrosion rate decrease with increase in concentration. The CR decrease from 37.59mm/yr to 27.50mm/yr in presence of the inhibitor. The CR also increase with increase in temperature up to 60oC. The increa...

TRANSLOCATION OF HEAVY METALS FROM SOIL TO VEGETABLES (SPINACH AND OKRA) IN IRRIGATED FARMS LAND BY NASARAWA TOTO RIVER BANKS IN NASARAWA STATE.

ABSTRACTThis study was conducted to investigate the level of translocation of heavy metals in vegetables(spinach and okra) with soils samples from farmlands irrigated with Nasarawa Toto River Bank water in Nasarawa state Nigeria. Using atomic absorption spectrophotometry(AAS), concentrations of Pb, Cd and Cr are determined in ten different farmlands were vegetables(spinach and okra) with soils were collected. The ranges of average concentrations of metals (mg/kg) of Pb and Cd in spinach...

DETERMINATION OF SOME SELECTED HEAVY METALS IN TOMATO (FRUITS AND LEAVES) AND ONION BULBS COLLECTED FROM HUNKUYI ROADSIDE FARMS, ZARIA.

ABSTRACT The concentration of heavy metals such as Pd, Cd, Cu and Cr were studied using AAS on vegetable samples such as Tomato (fruit and leaf) and Onion bulb. Trace element as Cu showed high concentration. The concentration of heavy metal like Cu ranged from of 0.155 to 0.024mg/kg in tomato fruit; 0.120 to 0.057mg/kg in leafy tomato; 0.118 to 0.121mg/kg in onion bulb which were more than the maximum permissible limit according to the International organization like FAO and WHO. The c...
