Abstract

Objective: To investigate the efficiency of biological agents used for the removal of calcium chloride in water under different parameters. Methods: The biosorbents prepared from the three fungi used in the present study were tested for their removal capacity of calcium from various concentrations of metal solutions at different pH values and different temperatures. Results: The present study indicates that out of the three organisms tested Rhizopus stolonifer has showed the efficiency of removing calcium from hard water and rendering them to moderate soft water quality at pH of 6 and temperature of 25 °C recorded at the higher concentration of 5 000 µg/mL of ground water and pure solutions. Conclusions: It can be concluded that the fungal biomass can show significant removal of metal ions than the conventional absorbents.
