New IACS Hydrogel Removes Toxic Dyes and Metal Ions
Researchers from the Indian Association for Cultivation of Sciences (IACS) have created a new hydrogel that effectively removes toxic organic dyes and metal ions from wastewater.
They found that the commonly used dyes, malachite green, congo red, brilliant blue and rhodomine B, all had begun to be absorbed within 15 minutes of exposure to the gel. In terms of metal ions, the scientists found that the industrial effluents cobalt and nickel were mostly removed from the water in six hours using the gel.
Such a discovery marks a positive step forward for water treatment, as the new method has high water permeability, large surface area for adsorption and ease of use.
