摘要
针对异烟酸-咝唑啉酮比色法测定水中氰化物步骤繁琐、耗电耗时这一缺点,通过试验对比得出在室温21℃左右时可以省略水浴,仅在室温下静置即可。本方法简便、实用,适用于监测地表水和污水中的氰化物。
This thesis is about how to improve determining cyanide in water with isonicotinic acid and pyrazolone. The original method waste time and electricity,and its steps and complicated. With experiments ,I have concluded that water bath can be omitted in about 21 ℃ temperature in the laboritory ,only place is still. The new method which both simple and practical can save electricity. It's suitable for determining cyanide in surface water and polluted water.
