| 摘 要： | 岩溶水中低含量氰化物的测定,应用气相色谱法是一良好的途径。本工作是在酸性溶液下,用溴将氰根转化为CNBr形式,利用电子捕获的高选择性,测定CNBr色谱峰。CN-在10~(-11)—10~(-9)克时获得良好线性。

Gas Chromatographic Determination of Cyanide in Karat Water |
| |
| Abstract: | A rapid and sensitive method for determination of small amounts of cyan-
ide in karst water by gas chromatography was studied. In acidic medium, CN-
could be converted into CNBr with bromine, and extracted with benzene. The
benzene extract was introduced through the chromatographic column and a
fine peak was obtained. A straight line was obtained over the range of 10-11-
10-9 gram of cyanide |
