摘要： An adsorbent of nitrohumic acid series with an improved alkali-resistance is prepared by insolubilizing calcium nitrohumate, kneading the insolubilized product with a water-soluble polyacrylamide in the presence of water, shaping the mixture into a desired form and then subjecting it to a heat treatment followed by an acid treatment. The adsorbent thus obtained can effectively be used for removing heavy metals from an alkaline effluent without causing any deterioration of adsorptive quality and coloration of the effluent.
