The experimental results showed that the denaturalized starch can be used as a kind of promising organic polymer coagulant-aid and absorbent. 通过实验结果说明，改性淀粉是一种很有发展前途的有机高分子助凝剂和吸附剂。
It also described the characteristic of SPE technique, preparing solid absorbents, packing absorbent tubes, breakthrough volume, safe sampling volume, as well as adsorption of SPE. 包括固相萃取的特点，固体吸附剂预处理，装填吸附管，漏点容量，安全采样体积及解吸。
