Transition metal ions in industrial effluent discharge are of great threat to the environment. Several conventional treatment technologies viz., ion exchange, membrane separation, ultra-filtration, ion flotation, electro-coagulation, electrodialysis, sedimentation and reverse osmosis have been employed. However these methods involve high operating cost and produce large volume of toxic chemical...

Present address: Department of Botany, R. T. M. Nagpur University, Nagpur (M.S.), India Abstract Mining industries frequently generates acid mine drainage (AMD) either by its operating or abandoned mines which are often characterized by an elevated levels of certain heavy metals, sulphate, low pH and some other toxic impurities in mine water creates environmental and ecological problems. Presen...

The potential of Pleurotus ostreatus spent mushroom compost (PSMC) as a green biosorbent for nickel (II) biosorption was investigated in this study. A novel approach of using the half-saturation concentration of biosorbent to rapidly determine the uptake, kinetics and mechanism of biosorption was employed together with cost per unit uptake analysis to determine the potential of this biosorbent....

Arsenic contamination in water poses a serious threat on human health. The tea fungus known as Kombucha is a waste produced during black tea fermentation. The objective of this study was to examine the main aspect of a possible strategy for the removal of arsenates employing tea fungal biomass. The pretreatment of biomass with FeCl3 was found to improve the biosorption efficiency. Arsenics upta...

Biosorption of Cd(II) ions from aqueous solutions by native and dried Oscillatoria sp. Cyanobacterium biomass was investigated in the batch mode. The Oscillatoria sp. was prepared from Molecular and Cell Laboratory of University of Mazandaran and grown in BG-11 medium. A comparison of Cd(II) adsorption properties of dried with native Oscillatoria sp. biomass was made, the dried one showed a hig...

The biosorption characteristics of Pb(II) and Cd(II) ions from aqueous solution using the macrofungus (Amanita rubescens) biomass were investigated as a function of pH, biomass dosage, contact time, and temperature. Langmuir, Freundlich and Dubinin-Radushkevich (D-R) models were applied to describe the biosorption isotherm of the metal ions by A. rubescens biomass. Langmuir model fitted the equ...

In this study, biosorption of heavy metal and dye by microbes will investigate. Optimum pH values of the maximum heavy metal biosorption will be finding. The bioremoval of the dye also investigate at different pH, Removal rates will measure respectively. The presence of heavy metal with dye analysis will be done for uptake by biosorbents .The results expected to indicate that the isolated bioso...

Pomegranate peel waste (PPW), a solid waste, was prepared and tested as biosorbent for the removal of a cationic dye, methylene blue (MB), from aqueous solutions by batch procedure. The effects of pH of solution, biosorbent dosage, contact time, and dye initial concentration on biosorption capacity were studied. MB uptake was favorable at pHs ranging from 5.0 to 12.0. The contact time required ...

This paper presents the biosorption of zinc from aqueous solutions using Gracilaria corticata (red algae) powder as a biosorbent. The equilibrium studies on biosorption of Zinc are carried out in batch process. The extent of removal depends on initial concentration of Zinc ion, pH, dosage, temperature etc. The optimum dosage is 15 g/L at the equilibrium agitation time of 60 min. The % biosorpti...

This research focuses on understanding biosorption process and developing a cost effective technology for treatement of heavy metals-contaminated domastic water. A new biosorbent has been prepared by crushing of neem leaves. The experiments were designed according to Taguchi’s (L16) orthogonal array to optimize experimental runs. In order to assess the biosorption behavior of neem leaves satisf...
