Journal ArticleDOI
Bioleaching of spent refinery processing catalyst using Aspergillus niger with high-yield oxalic acid.
Deenan Santhiya,Yen-Peng Ting +1 more
TL;DR: Overall, this study shows the possible use of bioleaching for the extraction of metal resources from spent catalysts and demonstrated the advantages of buffer-stimulated excretion of organic acids by A. niger inBioleaching of the spent catalyst.
Journal ArticleDOI
Use of adapted Aspergillus niger in the bioleaching of spent refinery processing catalyst
Deenan Santhiya,Yen-Peng Ting +1 more
TL;DR: Ni:Mo:Al-adapted strain was the most efficient in the leaching of metals from the catalyst over 30 days due to its tolerance to the toxic elements at 1 wt%.
Journal ArticleDOI
Surface chemical studies on sphalerite and galena using extracellular polysaccharides isolated from Bacillus polymyxa.
TL;DR: Fourier transform infrared spectroscopic studies provide evidence in support of hydrogen bonding and chemical interaction for the adsorption of ECP onto galena/sphalerite surfaces.
Journal ArticleDOI
Surface chemical studies on the competitive adsorption of poly(acrylic acid) and poly(vinyl alcohol) onto alumina
TL;DR: The adsorption of poly(acrylic acid) and polyvinyl alcohol (PVA) onto alumina has been studied as a function of pH, both individually and in the presence of each other.
Journal ArticleDOI
Effect of polymer molecular weight on the absorption of polyacrylic acid at the alumina-water interface
TL;DR: In this article, the absorption and electrokinetic properties of alumina suspensions in the presence of polyacrylic acid as a dispersant have been studied and the adsorption isotherms exhibit high affinity Langmuirian behaviour.
