Next came the tests and the team took the polymer to the river Ganga near Varanasi and tried it on the textile- industrial waste that enters the river. The results were replicated. Compared to conventional effluent-treatment methods, the polymer is a time-saving technique, says Balasubramanian. The added advantage of the polymer is that it can be reused after recovering the gold ions. "An Ethiopian student, Andrew Andarge, told me that water in his country contains toxic chromium where the polymer may find great use. We also plan to make use of the polymer in the Mula and Mutha rivers," said Balasubramanian.
