Biosorption of cadmium from water using surfactant impregnated eggshell
(EARET, 2018)Cadmium (Cd) is regarded as one of the most toxic elements and it causes water pollution when it exceeds the permissible limit. It is currently present in the Mooi River above these permitted levels, and must therefore ... -
Hydrothermal synthesis, characterization and adsorption testing of MoS2-Zeolite for the removal of lead in an aqueous solution
(EARET, 2018)The shortage of water can be worsened by the pollution of limited water resources by industrial activities such as mining which contribute to significant level of toxic heavy metals in the environments. Heavy metals ... -
Removal of malachite green and toluidine blue dyes from aqueous solution using a clay-biochar composite of bentonite and sweet sorghum bagasse
(RIP, 2019)A clay-biochar composite was prepared through slow pyrolysis of a mixture of bentonite clay and sweet sorghum bagasse. The adsorption of cationic dyes, namely, toluidine blue (TB) and malachite green (MG), by the ... -
Response of bacterial biosorbents to chemical treatment as influenced by cell membrane structure and impact on the adsorption behaviour of dyes
(Current Science Association, 2018)The impact of cell membrane structure and adsorption capacity of dyes due to chemical treatment on Gram-positive and Gram-negative bacteria was studied. The adsorption was found to occur through a chemisorption mechanism. ... -
Synthesized af-PFCl and GG-gP (AN)/TEOS hydrogel composite used in hybridized technique applied for AMD treatment
(Elsevier, 2018)In the present study af-PFCl, GL-g-P(AN) hydrogel and GL-g-P(AN)/TEOS hydrogel composite were synthesized. The hydrogels were characterized using the fourier transformed infra-red (FTIR) and the scanning electron microscope ... -
Visible light-excitable ZnO/2D graphitic-C3N4 heterostructure for the photodegradation of naphthalene
(Balaban Publishers, 2019)In this study, ZnO/g-C3 N4 heterostructure was synthesized with enhanced photodegradation potential for polycyclic aromatic hydrocarbons (PAHs) (viz. naphthalene) in water using visible light. The as-prepared catalysts ...
