Method of treating viscose plant wastewaters with coal wastes
- 20 Downloads
Humic acids were separated from oxidized coals with a minimum yield of 50%. It was shown that sodium humate can be used for precipitating zinc from viscose plant wastewaters. Regardless of the concentration and pH of the wastewater, zinc is totally extracted from it. The zinc can be desorbed from the humate sediment in the form of zinc sulfate.
