Synthesis and Characterization of Zeolite-Goethite Nanocomposite

Adegoke H. I.*, Bello M. O., Dolapo A. F.

In recent years, nanocomposite materials have received much interest in nanotechnology. This new trend in nanotechnology is aimed at producing materials of unique properties. In view of this, zeolite goethite nanocomposite was synthesized to reinforce zeolite properties. Zeolite was synthesized hydrothermally from sodium aluminate, sodium silicate and sodium hydroxide at 100 oC for 24 h. The compo...

Zeolite NaY from Kankara Kaolin using Commercial Grade Chemical: Effect of Crystallization Time and Temperature

Ajayi O. A*, Mamman J., Adefila S. S.

Zeolite Y was synthesized using commercial sodium hydroxide and Kankara kaolin as starting material in the presence of sodium silicate formed from kaolinite clay. Synthesis was done at 90°C, 95°C and 100°C for crystallization time of 12, 18, 24 and 36 hours. Results showed that commercial sodium hydroxide could be used to successfully produce zeolite Y from Kankara kaolin when gelling ratios of...

Evaluation of Bagasse Ash for Application in Glass Manufacture

Tagwoi J. T.*, Garkida A. D., Ali E. A., Asuke F., Yawas D. S.

Bagasse ash results from burning bagasse, a matted cellulose fiber residue from sugarcane that has been processed in sugar mills. In this paper, Bagasse ash has been chemically characterized in order to evaluate the possibility of its use in glass manufacture. The result of X-ray fluorescence (XRF) showed the ash to contain SiO2 - 31.67%, K2O - 31.41%, P2O5 - 8.14%, MgO - 4.89%, CaO - 3.92%, N...

Health Risks Assessment of Heavy Metals in Noodles Sold in Ozoro, Delta State, Nigeria

Emumejaye K.*, Daniel-Umeri R. A., Edema O. G.

The concentrations of some selected heavy metals were assessed by atomic absorption spectrophotometry in noodles sold in the study area. Total of eight different brands of noodles were investigated. The results of heavy metals in samples in mg/kg were in the order: Fe (13.15 – 144.75); Pb (0.00 – 0.55); Cd (0.00 – 0.01); As (0.00 – 0.14); Ni (0.01 – 0.09); Cu (0.02 – 0.33); Zn (1.45 – 8.05) an...

Kinetics Studies of the Removal of Manganese, Cadmium and Lead from Aqueous Solution Using Cocoa Shell

Ojiodu C. C.*, Eruola A. O., Olowu R. A.

The kinetics of the removal of manganese cadmium and lead in aqueous solution using cocoa shell as an adsorbent was investigated. The effect of contact time, kinetic of sorption mechanism and the adsorbate concentrations on sorption of Mn2+, Cd2+ and Pb2+ ions were examined. The kinetic of the sorption mechanism of Mn2+, Cd2+ and Pb2+ was evaluated using pseudo-first order (Lagergren) rate and...

Investigation into the Admixture Properties of Bone Ash: A Focus on Setting Time of Ordinary Portland Cement

Mtallib M.O.A.*, Tijjani D.

This paper reports the findings of an investigation into the admixture potential of bone ash (BA) with a focus on the setting time of ordinary Portland cement (OPC). Cow bones are agricultural waste and constitute a sizeable proportion of solid waste in many cities of the world. Heaps of cow bones constitute aesthetic problem to the environment, unnecessary occupation of space and exude unpleasant...

Photo-Degradation of Direct Yellow 96 In UV/TiO2 and UV/H2O2 using Factorial Design

Okeme A. C.*, Kogo A. A., Nurudeen Yusuf., Abdulraheem Giwa

In this research, factorial design have been employed to study the influence of four important factors; pH, catalyst dosage, irradiation time and dye concentration in the treatment of C.I. Direct Yellow 96 dyestuff using UV/TiO2 and UV/H2O2 photo-degradation processes. The results indicate that the adsorbent dosage and irradiation time exhibit a significant positive effect on the efficiency of ...
