【摘要】 研究了活性炭吸附高铼酸铵的性质,在15℃时,测得高铼酸铵(NH4ReO4)的溶解吸热量为-44.34kJ/mol;15.5℃时,高铼酸铵的吸附放热量为53.31kJ/mol。两个数值比较,说明活性炭吸附高铼酸铵在常温下属于物理吸附。

【Abstract】 The adsorption of NH4ReO4 on active carbon was investigated by the direct calorimetry. The dissolving heat of NH4ReO4 was measured to be -44.34kJ/mol at 15℃,while the adsorption heat of NH4ReO4 on active carbon was 53.31kJ/mol at 15.5℃,which indicated that the adsorption of NH4ReO4 on active carbon is physisorption.
