In the present study we reported the feasibility of Pseudomonas alcaligenes biomass as an alternative biosorbent to remove Pb(II) metallic ions from environmental and industrial wastewater. The ability of Pseudomonas alcaligenes to remove the metallic ions was investigated by using batch biosorption procedure. The effects such as, pH, biosorbent dosage, sorbate concentrations and sorbate-sorbent contact...
In the present study we reported the feasibility of extracellular biopolymer (PF-9) produced by Pseudomonas fluorescence C-9 as an alternative biosorbent to remove Pb(II) metallic ions from environmental and industrial wastewater.The ability of PF-9 to remove the metallic ions was investigated by using batch biosorption procedure. The effects such as, pH, biosorbent dosage, sorbate concentrations...
In this work, chemically oxidized mesoporous carbon (COMC) with excellent lead adsorption performance was prepared by an acid surface modification method from mesoporous carbon (MC) by wet impregnation method. The structural order and textural properties of the mesoporous materials were studied by XRD, SEM, and nitrogen adsorption. The presence of carboxylic functional groups on the carbon surface...
The adsorption of copper and lead on MnO2 was followed by monitoring the frequency of piezoelectric crystal coated with MnO2 in contact with solutions of the metal under study, at controlled temperature. Each isotherm was constructed for concentrations of each metal between 1 and 58 mg L-1. When absorption data for copper or lead were fitted to the Langmuir isotherm, two linear zones were obtained,...
