AI Technical Summary
Existing drinking water purification technologies are ineffective at removing bacteria and microbial contaminants from water, and traditional methods suffer from limited purification effects, resource waste, and high energy consumption.
A composite drinking water purifier was prepared by calcining activated carbon, mixing it with water, centrifuging and washing it to remove the surface graphite, then adsorbing polydopamine onto the surface of the activated carbon, and coating it with a layer of cystine. This purifier is used to purify water, reduce turbidity and improve the removal of bacteria.
The prepared composite drinking water purifier can significantly reduce the turbidity of water, with a removal rate of 73.1%, and avoids resource waste. It has the largest adsorption kinetic coefficient of 462 cm3/g, and the adsorption rate reaches its maximum at a working concentration of 123 mg/L and a time of 4 hours.
