Carbon nanotubes after oxidation and purification were used to pack a micro-column which was incorporated into a sequential injection system for facilitating online selective sorption of lysozyme from egg-white. The retained protein was afterwards quantitatively eluted by a carbonate buffer. With a sample loading volume of 2.0 mL, an enrichment factor of 12 was obtained, along with a retention efficiency of 100% and a recovery rate of 100%.

According to the results of the former study in our laboratory, trans-1, 2-cyclohexanediol is produced with a lot of acids and water, for extraction of trans-1, 2-cyclohexanediol from the solution, ethyl acetate and butyl acetate were used as extraction reagents, the solubility data of the trans-1, 2-cyclohexanediol in corresponding mixed solvents of some sorts of acetates and water are needed.

根据本实验室前期研究结果可知，反式-1，2-环己二醇是在酸性和大量水存在的条件下得到的，为了把反式-1，2-环己二醇从反应液中萃取出来，本工艺所采用的萃取剂是乙酸乙酯和乙酸丁酯，需要获得反式-1，2-环己二醇在这些酯类与水混合溶剂中的溶解度数据，因而对反式-1，2-环己二醇进行相关固液相平衡的研究是非常迫切和必要的。

Experimental results indicated that the contaminants generally existed in mussel, such as α-HCH,β-HCH,γ-HCH,δ-HCH, o·p-DDT, p·p-DDT, p·p-DDD, were degraded completely under the above conditions, whereas DDE, aldrin and dieldrin were partly degraded. No detectable degradation of PCB 1242 and PCB 1248 were observed. Thus the conventional preparation of the contaminants using the columns packed with Florisil or SiO〓 could be left out.

测定贻贝中的PCBs时，以KOH甲醇溶液处理试样，在微波能作用下，试样的微波皂化与有机氯农药的微波碱解同时进行；测定土壤和沉积物中的PCBs时，以KOH甲醇溶液处理试样，在微波能作用下，PCBs的微波萃取与有机氯农药的微波碱解同时进行，1M KOH甲醇溶液对PCBs的微波萃取能力与纯甲醇溶剂相当。
