The commercial sodium pentachlorophenolate contains various impurities, such as tetrachlorophenol, but the method of purification had not been established.　Then, in order to carry out a series of studies on the pentachlorophenol and its derivatives, the authors have investigated on the method of purification and determination of the commercial sodium pentachlorophenolate.　Following results were obtained.　(1) By the sublimation and recrystallization method, the pure pentachlorophenol has been obtained from the commercial sodium pentachlorophenolate.　(2) Among the methods investigated for the determination of sodium pentachlorophenolate, potentiometric titration method with AgNO_3 gives the most accurate results.　(3) By the addition of suitable amount of Ca(NO_3)_2, commercial sodium pentachlorcphenolate can be determined with the potentiometric titration method.
