摘要
报道了麦饭石对水溶液中铵的吸附规律.结果表明,在一定时间内.当铵浓度相同时,吸铵率随麦饭石粒度的减小而增大;在麦饭石粒度及用量一定时,则随铵浓度的增加而增大.麦饭石对水体pH值有双向调节功能,使低pH值水体pH值上升,使高pH值水体pH值下降,最终稳定在8.0~8.5之间.测定了麦饭石对铵的饱和吸附量为0.243mmol/g.
The present paper first introduces the adsorptive characteristics of ammonia in aqueous solutions on Mat Fan Stone. The results show that the adsorption rate of ammonia in solution on Mat Fan Stone increases with the decrease of the stone's size when time is fixed,ammonia concentrations are the same; and increases with the increase of ammonia concentrations for fixed stone quantity and size. The saturated adsorptive density was 0. 243 m mol/g in aqueous solution ammonia on Mat Fan Stone.
