“The hydrogel is responsive to changes with the acid and base content of the water. Addition of acid breaks the gel. It again reconstructs upon addition of alkaline solutions. This means the
hydrogel can be reused multiple times by just changing the acid level. This could bring down the cost of wastewater treatment substantially. Further, the separation was found to be much
faster than the conventional methods,” said professor Tapas Maji, leader of the research team, while speaking to _India Science Wire_.
