近年来,在许多元素的分光光度测定法中应用阳离子表面活性剂作胶束增溶剂以提高光度测定的灵敏度和选择性。四条好雄等应用胶束增溶剂——十六烷基三申基氯化铵以提高苯芴酮法测定锗的灵敏度,但该文未进行千扰元素的影响等试验和试样分析。我们采用十六烷基三甲基溴化铵(以下简称CTAB)作试验,研究了它的显色条件、干扰元素的影响以及试样分析等。本法的灵敏度较动物胶为稳定
In recent years, cationic surfactants have been used as micelle solubilizers in many elemental spectrophotometry to increase the sensitivity and selectivity of photometric assays. Four good male and other application of micellar solubilizer - cetyl trinitrate ammonium chloride to improve benzene benzofluorenone method for the determination of germanium sensitivity, but the article did not interfere with the elements such as the impact of test and sample analysis. We use cetyl trimethyl ammonium bromide (hereinafter referred to as CTAB) as a test, studied its color conditions, the impact of interference elements and sample analysis. The sensitivity of this method is more stable than that of animal glue
