活性炭对磷吸附作用的研究

A Study on the Absorption of Active Carbon to phosphorus

在磷标准溶液中加入一定量的活性炭，采用钼蓝法进行比色测定，比较在有ＨＣＯ存在下和无ＨＣＯ存在下磷的吸附情况。实验结果表明：活性炭对磷有明显的吸附作用。但在磷标准液中加入０．５ｍｏｌ·Ｌ－１ＮａＨＣＯ３溶液后，则活性炭对磷的吸附量明显减少。

The cbsorption of phosphorus by putting some active carbon into standard phosphorus liquid both with and without HCO by colorimetric andlysis of molybclenum blues. The result showed that active carbon adsords phosphorus obviously, but it becomes less when putting NaHCO3 into the standard phosphorus liquid.
