从钨钼废液中除铬的实验研究
EXPERIMENTAL STUDY ON CHROMIUM REMOVAL FROM WASTE LIQUID CONTAINING TUNGSTEN AND MOLYBDENUM
摘要
Abstract
For waste liquid containing tungsten,molybdenum,chromium from waste high-temperature alloy from which tungsten and molybdenum were recovered,chromium was removed by chemical reduction method.The reaction conditions are:reduction of initial pH was 1,the reducing agent Na2SO3 excess coefficient of 12,reduction time 1 h,reduction temperature 25 ℃,under this condition,the content of Cr in waste liquid containing chromium is reduced to less than 0.05 mg/L.关键词
