Water purification using different waste fruit cortexes for the removal of heavy metals

Removal of heavy metals from waste water using different biosorbents

The discharge of waste water containing heavy metals like Cr, Cd, Cu from tanneries, electroplating units, metal processing industry etc is the major cause for metal pollution which in turn causes adverse effects in the environment. The conventional methods available for removal of heavy metal are costly and also produce some toxic sludge. This has lead to the invention of new technology like b...

Removal of Heavy Metals from Waste Water Using Water Hyacinth

-Water pollution has become one of the most serious problems of today’s civilization. In the last few years considerable amount of research has been done on the potential of aquatic macrophytes for pollutant removal or even as bio-indicators for heavy metals in aquatic ecosystems. Water hyacinth is one of the aquatic plant species successfully used for wastewater treatment. It is very efficient...

Waste Biomaterials for Removal of Heavy Metals – An Overview

Environment fortification must require the use of natural products instead of chemicals to minimize pollution. The detoxification of metal pollutants from wastewater by the development of biomaterials having higher affinity, capacity and selectivity had been found to be as an alternative over conventional technologies that were often inadequate to reduce concentrations in wastewater to acceptab...

Heavy Metals in Waste

Genetic risk assessment of acid waste water containing heavy metals.

The mutagenic/cancerogenic potential of acid-mine water from the Slovak mining area Rudnany containing a high load of toxic metals was evaluated after its application to three model test organisms (bacteria Salmonella typhimurium, yeast Saccharomyces cerevisiae and plant Vicia sativa L.). The results obtained from the modified preincubation Ames assay proved that 1000-fold diluted waste water e...
