As an effort to contribute to knowledge on adsorption onto environmentally friendly adsorbents the removal of BOD and COD of vegetable oil industry effluent using chemically prepared activated carbons from Telfairia occidentalis Hook. F (fluted pumpkin) was investigated under batch and column experiments. Batch adsorption had better performance with BOD and COD removal of 52% to 83% while column...

Abstract The corrosion inhibition of aluminum in alkaline medium was studied using experimental methods. Results obtained from the gravimetric method indicate that the extract is an excellent corrosion inhibitor. The adsorption of the inhibitor on the surface of aluminium is consistent with the Langmuir isotherm. Physical adsorption mechanism is proposed from the calculated thermodynamics...

Abstract The influence of naturally occurring extract of Balanites aegyptiaca on the corrosion inhibition of Aluminium Alloy in sulphuric acid is studied by gravimetric method, thermometric method and IR studies. The experimental results revealed that extract has good inhibiting effect on the metal on 0.1M H2SO4. The protection efficiency increases with increasing inhibitor concentration to...

Quantitative determination of aflatoxin B1 and total aflatoxin in African locust bean condiment samples consumed in Kaduna metropolis was investigated in this study. Elisa kits were used to measure Aflatoxin B1 and total aflatoxin. Samples for analysis were obtained by stratified random sampling method with central market, Monday market, kawo market and mando market identified as the sampling...

50 different brands of artemether/lumefantrine was used for this study. TLC and HPLC were used to assess the quality of these drugs. With the physical test, all products passed the uniformity of weight and disintegration time test, but one tablet BD 03 failed the friability test. From the results of TLC and HPLC analysis, artemether/lumefratine content were very close to the labelled amount. The...

Abstract The plant extracts are biodegradable, eco-friendly, cheap, readily available, non-toxic and easily assessable source of material which can be used as corrosion inhibitor for Aluminium Alloy in acidic medium. The effect of the plant was investigated by theoretical method. Highest occupied molecular orbital (HOMO), lowest unoccupied molecular orbital (LUMO), dipole moment, ionization...

Abstract The effect of the ethanolic extract of Balanites aegyptiaca on the corrosion of Aluminium in alkaline medium was studied by weight measurement, thermometric method, IR studies and theoretical methods. Results from the aforementioned method strongly suggested that the plant extract is a good corrosion inhibitor. The adsorption of the inhibitor on the surface of the metal is in...
