摘要
Pulp mill bleach effluents are decolorized, after a suitable lime treatment, by acidifying to a pH of about 1-5 and thereafter passing the acidified effluent through a bed or mass of a macroreticular adsorbent resin. The macroreticular adsorbent resin may be aromatic or aliphatic in character and has a porosity of at least 10 percent and a specific surface area of at least 10 square meters per gram.
