IIT Bombay team removes heavy metals from water with greater efficiency

IIT Bombay researchers have fabricated a carbon-based nanostructure that is capable of simultaneously adsorbing with very high efficiency four heavy metals — arsenic, chromium, cadmium and mercury — from wastewater. The nanostructure can be recycled and reused multiple times. Simultaneously removing heavy metals such as arsenic, chromium, cadmium and mercury from waste water with very … Continue reading IIT Bombay team removes heavy metals from water with greater efficiency

IIT Jodhpur fabricates a highly sensitive device for lead detection

Researchers at IIT Jodhpur have fabricated a portable sensor for detecting lead in water. It can detect lead even when present at extremely low concentration of 0.018 ppb, much lower than the WHO limit of 5 ppb for drinking water. A highly sensitive, portable device that can detect the presence of lead in water even … Continue reading IIT Jodhpur fabricates a highly sensitive device for lead detection

CLRI’s biocatalyst cuts effluent discharge during leather processing

A novel biocatalyst developed by researchers at CLRI, Chennai speeds up the leather processing time at the pre-tanning stage, cuts chromium usage, and achieves three-fold reduction in water usage thus reducing waste discharge. A novel amylase-based biocatalyst developed by researchers at the Central Leather Research Institute (CSIR-CLRI), Chennai helps in the processing leather in an … Continue reading CLRI’s biocatalyst cuts effluent discharge during leather processing

CSMCRI uses seaweed to remove lead, chromium and dyes from wastewater

Researchers at CSMCRI have used functionalised seaweed nanocomposite to remove lead and chromium from wastewater. The adsorbed lead did not leach out even in low pH conditions. The nanocomposite was also able to completely remove dyes that are commonly used in textile industry. Removing toxic metals such as lead and chromium and certain dyes from … Continue reading CSMCRI uses seaweed to remove lead, chromium and dyes from wastewater

Kolkata scientists use fungus to remove toxic chromium from tannery waste

The heat dried fungal biomass adsorbs toxic hexavalent chromium from untreated tannery waste and converts it into non-toxic trivalent chromium thus solving the problem of disposing toxic chromium waste. Removing hexavalent chromium [Cr(VI)] from industrial effluents, particularly untreated tannery waste, will become easier and more efficient, thanks to the work by a team of researchers from … Continue reading Kolkata scientists use fungus to remove toxic chromium from tannery waste
