Water quality . determination of monomethyl hydrazine . p - dimethylaminobenzaldegyde spectrophotometric method 水质-甲基肼的测定对二甲氨基苯甲醛分光光度法
The merits and shortcomings are analyzed of the paradimethylaminobenzaldehyde method and the diacetyl monoxime method in their application to the determination of trace urea in the urea hydrolytic system 摘要分析了对二甲氨基苯甲醛法和二乙酰单肟法在尿素水解系统微量尿素分析中应用的优缺点。
( 2 ) the method of determining the concentration of tbh is studied in this paper . the concentration of normal - amount tbh can be determined by kios oxidation . the presence of hnoa in the titration media has no effect on the tritration results . the concentration of trace - amount tbh can be determined by colorimetric methodising paradimethylaminobenzaldehyde as a color reagent ( 2 )研究了tbh浓度的测定方法。 kio3氧化法能有效测定常量tbh的浓度, tbh溶液中存在一定浓度的hno3时对滴定结果没有影响。以对二甲氨基苯甲醛为显色剂,采用比色法能测定微量tbh的浓度。
