Disarmament of micropollutants from wastewater using nylon waste/chitosan blended with algal biomass as recoverable membrane

In the current approach, a recoverable/bio-resistant membrane was innovatively prepared to be applicable in removal of Cu+2 and Pb+2 ions as water micropollutants. Nylon waste was currently exploited for removal of micropollutants, as low cost and ecofriendly alternative candidate for water treatmen...
