在树脂化学组分的鉴定中,常需作元素分析,尤其是氯的分析。测定聚合物氯含量的技术颇多,其中有些已立为规范和标准了,但对简陋的实验室来说,若要采用这些技术还是困难的,往往需要去寻找稀缺的试剂或添置复杂的设备,这是各种定氯法所共 In the identification of resin chemical composition, often for elemental analysis, especially chlorine analysis. There are a number of techniques for measuring the chlorine content of polymers, some of which have been established as norms and standards, but for crude laboratories to use these techniques is still difficult, often need to find scarce reagents or purchase complex equipment This is a total of a variety of fixed chlorine method
