三价铬的脱除过程是吸附剂多孔道大表面的吸附作用。随着pH增大，三价铬有生成氢氧化铬的倾向，同时吸附剂表明官能团的去离子化，也有利于三价铬的吸附。

The removal process of trivalent chromium is a kind of adsorption on adsorbent’s porous surface. Along with pH value increasing, trivalent chromium tends to become chromium hydroxide, and the deionization of functional groups on adsorbent’s surface at the same time also benefits to the adhesion of trivalent chromium.
