摘　　要：该文采用在线中和装置去除氢氧化四丁基铵(TBAOH)中氢氧根对阴离子测定的干扰,然后用离子色谱法对几种TBAOH中的F-、Cr-、NO3-等痕量阴离子进行测定。样品测定结果比较满意,回收率在87．68％-109．4％之间。该方法具有很高的选择性和灵敏度。An on--line neutralizing apparatus is used to remove OH^- from TBAOH, so as to prevent the disturbance of OH-- in determining other anions. And consequently the determination of some trace anions such as F^- , Cl^- , and NO^3- etc. is carried out, in which the ion chromatograph is employed. The result shows that the recovery rate of the present work is between 87. 68% -109. 4%. The analytical method of the present study exhibits both good selectivity and high sensitivity.
