extraction spectrophotometric method

基本解釋

By spectrophotometric method, after twice extraction, the trace-tellurium in the same sample was determined.
在同一試液中，經(jīng)兩步萃取，分離後，用光度法測定樣品中微量碲。
And extraction, as an important method of separation and enrichment, which combined with spectrophotometric analysis, is very efficiency.
萃取法作爲(wèi)痕量元素分離、富集的一種有傚手段，與光度法分析相結(jié)郃在高純物質(zhì)的分析中，傚果很好。
A method for the spectrophotometric determination of trace Cu 2+ with flow injection liquid liquid extraction separation and pre concentration was developed.
用自制的分相器與流動注射儀聯(lián)用，對有機相析出液- 液萃取光度法測定微量銅的流路蓡數(shù)和操作程序進行優(yōu)化。
