Assessment of the Effect of Hydrolysed Starch Graft CopolymersApplication on Soil Nutrient (Phosphorus and Nitrogen) Retention

The effects of the application of the graft copolymers (Hydrolyzed starch-g-polyacrylonitrile (HSPAN) and Hydrolyzed starch-g-polyacrylic acid (HSPAA)) on the nitrogen (N) and phosphorus (P) retention capacity of soil was evaluated in this study. Soil nutrient (N and P) retention capacity tests was carried out at three graft copolymers application rates (3.0, 6.0, and 9.0g/kg soil) against a blank soil sample to which graft copolymers was not applied. Diammonium phosphate (DAP) at 0, 100, and...

Response Surface Methodology for the Competitive Sorption of Metal ions from Aqueous Medium using Starch-Graft-Copolymer

The competitive sorption of Cu (II), Pb (II) and Cd (II) by graft copolymer of cassava starch and acrylic acid was investigated using the response surface methodology. Optimization of the medium conditions was studied through experimental design. Response surface methodology including central composite design was successfully applied to develop a response surface to optimize the medium conditions. The most influential medium parameters were determined as initial concentration, contact time an...

Equilibrium, Kinetic and Thermodynamic Studies Of Lead (II) Sorption on Hydrolyzed Starch Graft Copolymers

Hydrolyzed starch graft poly (acrylic acid) and starch graft poly(acrylonitrile) copolymers were used as a sorbents for the removal of Pb(II) from aqueous solution in batch process. The sorbents were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy and thermogravimetric analysis. The effect of contact time, initial concentration and temperature were assessed to optimize the conditions for maximum sorption of the metal ions. The experimental data were anal...

COMPETITIVE SORPTION OF Cd (II), Pb (II) AND Cu (II) IONS ON HYDROLYZED STARCH GRAFT COPOLYMERS

Hydrolyzed starch graft copolymers of acrylic acid and acrylonitrile were used as a sorbents for the competitive removal of Pb (II), Cd (II) and Cu (II) ions from aqueous solution in batch process. The sorbents were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, wide-angle x-ray diffractometer and thermogravimetric analysis. The equilibrium sorption properties were assessed to optimize the conditions for maximum competitive sorption of the metal ions. ...

Effects of Snail Shell as Filler on the Mechanical Properties of Terephthalic Unsaturated Polyester Resin

The mechanical properties of snail shell reinforced unsaturated polyester composite was assessed in this study. Ground snail shells of particle size 65μm were introduced at different percentages into the unsaturated polyester resin. The powdered shells were characterized using FTIR to determine the functional groups present. The tensile test was performed using an Instron universal testing machine operated at a cross head speed of 10mm/min. The tensile test specimen preparation and testing p...

EFFECTS OF POLYETHYLENE GLYCOL AS ALTERNATIVE ACTIVATOR IN A BAMBOO FIBRE FILLED NATURAL RUBBER COMPOSITE

There is a growing interest in the research community of the possibility of reducing or total elimination of zinc oxide (ZnO) as activator in rubber compounds. This study therefore is an attempt in that direction to study the effect of polyethylene glycol (PEG) as an alternative activator in rubber compounds. Various levels of polyethylene glycol (0,2,3,4,5,6 phr) and zinc oxide (as reference) were compounded with 100phr of natural rubber and other compounding additives. The effects of both p...

EVALUATION OF THE CONCENTRATION OF SOME METALS (Pb,Zn,Mg,Fe) IN DIETARY RED PALM OIL PRODUCED IN SOME LGA IN ABIA STATE

Palm oil has been part of human diet for more than 5000 years. Nigeria is currently the fifth world’s leading producer of palm oil (Nnorom, 2012). The palm oil industry is a major agro based enterprise in Nigeria especially in the southern part where palm oil trees are found both in the wild land plantations (Nwaugo et al., 2008). For generations, it has been revered as both a nutritious food and a valuable medicine. However, care should be taken to evaluate the purity and safety of this nu...

Synthesis, Characterization of Acid Orange 7 Dye on Cellulose Acetate Biopolymer

ABSTRACT The present paper describes the synthesis of Acid Orange(7)dye which can be used as dyes for cellulose acetate biopolymer. They were obtained by the diazotization of a monoazo component of the mono-azobenzene type, followed by coupling. The monoazo components were obtained by the diazotization of sulphanilic acid and coupling with 2-naphthol. The synthesized dye was later analyzed by GC-MS, IR and UV-Vis spectrometry. The dyeing performance of the dye was evaluated on cellulose aceta...

Drug Release Agents

          ABSRACT The purpose of this research work was to examine drug release agents and the several delivery systems for which both natural and synthetic polymers have been employed for their design and fabrications. Under these facts, a large number of delivery systems made from synthetic polymer materials were found to be non-biodegradable, non-biocompatible and thus tend to impose both adverse mechanical and physiological effects on man when consumed especially on respiratory proce...

Jatropha Tanjorensis Leaf Extract as an Environmentally Friendly Mild Steel Corrosion Inhibitor in Acidic Medium

Abstract : The inhibition of the corrosion of mild steel in 1 M H2SO4 solution by Jatropha tanjorensis leaf extract (JTLE) has been studied using weight loss and hydrogen evolution techniques. The results obtained reveal that JTLE effectively inhibited the corrosion of mild steel in H2SO4 solution. The highest inhibition efficiency of 89.73% occurred at 5.0 g/L JTLE concentration at 333K by weight loss measurements. Inhibition efficiency was found to increase with increase in JTLE concent...
