Fabrication and Characterization of Zeolites and its Application in Heavy Metal Capture

ABSTRACT Zeolite crystals were synthesized by mixing sodium silicate and sodium aluminate to obtain aluminosilicate gel which was further treated hydrothermally to obtain the final product. The zeolite crystals were characterized by x-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD result identified the synthesized crystals as zeolite z; additional evidence was provided by the SEM images which showed that the zeolite crystals were disc-shaped and the particle sizes rang...

Total Alkaloids, Total Tannins Content and Antiulcer Assay of Four Selected Medicinal Plants.

ABSTRACT The total alkaloid, tannins contents and antiulcer activity of the extracts from four selected medicinal plants were investigated. The total alkaloids content (TAC) was evaluated according to the chloride colometric method in which atropine was used as standard. While the total tannins content (TTC) was also determined using Folin Ciocalteau assay in which gallic acid was used as a standard. The antiulcer activity of the extracts was investigated using the ethanol induced model in wi...

ABSTRACT The highly nucleophilic bridging sulfide centers in bis(μ-sulfido)tetrakis(triphenylphosphine) diplatinum(II), [Pt2(µ-S)2(PPh3)4] enables the incorporation of any organic functionality (R) through facile monoalkylation to form cationic complex [Pt2(µ-S)(µ-SR)(PPh3)4] + . The organic electrophiles; N,N’-(2-dichloroethyl) piperazine-4-carboxi-amine, N-(2-chloroethyl) morpholine4-carboxi-amine, and N-(2-chloroethyl)-1-methylpiperazine-4-carboxi-amine derived from isocyanate were s...

Production, Optimization and Application of Printing Ink from Waste Carbon Sources

ABSTRACT Production of carbon black from novel sources like spent automobile tyre, anthracite coal, furnace soot and graphite rod and subsequent use in the production of offset printing inks has been investigated. Carbon black from these sources were obtained by pyrolysis of shredded spent tyre and coal samples at 750-900o C in an electrical furnace, isolation of furnace carbon black and graphite rod from dry cell, drying and pulverization of the resulting samples. Acid demineralization of th...

Synthesis and Biological Activities of Phenylsulphonylaminoalkanamides

ABSTRACT Palladium catalysed synthesis of substituted 2-[acetyl(phenylsulphonyl)amino]-3- methylbutanamide (176) is reported. The intermediate 2-[acetyl(phenylsulphonyl)amino]-3- methybutanamide (175) was obtained by the reaction between 2-[acetyl (phenylsulphonyl)amino]-3-methybutanoic acid chloride (175) and ammonia. Substituted 2- [acetyl (phenylsulphonyl)amino]-3-methylbutanamides (176a-f) were obtained by coupling 2-[acetyl (phenylsulphonyl)amino]-3-methylbutanamide (175) with various re...

Phytochemical Quantification, Antioxidant and Antimicrobial Activities of Root Extracts of Dennettia Tripetala and Milicia Excelsa.

ABSTRACT The roots of Dennettia tripetala and Milicia excelsa were analyzed for the presence of phytochemicals. Five different solvents, which include methanol, ethanol, ethyl acetate, butanol and water, were used for the extraction of the phytochemicals.The root of Dennettia tripetala contained alkaloids, terpenoids, flavonoids, saponins, phenols, steroids and glycosides in varying degrees of abundance in the different solvents with tannins not detected in all the solvents. Milicia excelsa c...

The Effect of 4-Acyl Substituents On the Infrared Stretching Frequencies of Some 1-Phenyl -3- Methyl -4- Acylpyrazol -5-Ones and Their Magnesium (Ii), Cobalt(Ii), Copper (Ii) and Zinc (Ii) Ch

ABSTRACT The divalent metal chelates of Mg,Co,Cu and Zn with 4-acetyl (hpmap), 4- benzoyl(hpmbp),4-butyryl(hpmbup),4-capyroyl(hpmcp),4-propiony (hpmprp) and 4-palmitoyl(hpmpp) derivatives of 1-phenyl -3-methyl pyrazol-5-one have been synthesized and characterized by UV ,IR, and conductivity measurements. It is shown that the ligands behaved like bidentate enols, all forming neutral chelates with the metal ions , bonding through oxygen of the enolic hydroxyl group and /or the oxygen atom of th...

A Survey of Industrial Pollution in Anambra State, An Assessment of Water Quality Parameters of Rivers Dodo, Oji and Ebenebe Lake

ABSTRACT A survey of industrial pollution in Anambra state WFS carried out between February A990 and June 1997, The survey showed that Idemili, Onitsha and Nnewi Local Government Areas h3ve the greatest concentration of industries* Some of these industries.: discharqe their wastes into the environment with very little or no tre3tment. ~histochemical characteristics of rivers godo, Oji and Ebenebe Lake were determined, The concentrations of some water-quality-parameters vi7, dissolved oxygen (...

Determination of Gold Concentration in the Gold Ore in Lujinji, Mubende District.

Abstract This study is aimed at determining the concentration of gold in the gold ore in lujinjimubende district. Currently investing in gold mining is taken as a riskyinvestmentbecause people are not sure of the concentration of gold in lujinji and also the depth where gold concentration is high. The results of this research gave the concentration of gold in lujinji and also the depth of high concentration from the surface, which eased the mining activity by extracting gold at a known height...

Assessment of Selected Pollution Indices of Domestic Wastewater Discharge from Kira Town Council, Wakiso.

ABSTRACT This study focuses on the temporal monitoring and analysis of wastewater from Kira Tocvn Council. The distribution of the chemical constituents major and minor is determined and compared with National Environment Management Authority (NEMA) Standards of wastewater discharge on land and into water bodies. The obtained results indicated that most of collected wastewater samples exceeded the acceptable limits set by standards used for most parameters determined. The wastewater parameter...

Effect of Asystasia Gangeticum (Atu ukwara) Leaves Extract on Fermentation Kinetics of Elaeis Guineensis (Palm wine)

The kinetic studies of Elais guineensis sap is of major important in determining the extent of preservation of palm wine, since production is highest in the rainy season. The effect of 0.1, 0.2, 0.4, 0.8 and 1.6% Asystasia gangeticum leaves extract (in order to inhibit the activities of microbes during fermentation of E. guineensis sap) on the rate of palm wine fermentation, using 100 mL portion of fresh palm sap was determined. The rate of fermentation is measured as the rate of carbon dioxi...
