【摘要】 水中硫化物不稳定,最好是现场即时测定。本文旨在研究现场快速测定水中的硫化物。本研究运用比色分析的朗伯-比尔定律和真空工艺设计,将复杂繁琐的实验室测试方法和操作程序有机的融合在测试管中。该测试管具有快速、简便和价格低廉等特点,测定范围0.1～10mg/L。更多还原

【Abstract】 S^2- in Water need be rapidly detected. A simple,rapid method for detecting S^2- in water is described. Based on the principle of chlorimetric analysis and vacuum process design, complex detecting method in lab. And operating procedure is associated into a determination tube. The time for detecting a sample needs only 10 min. The cost of this method cuts heavily. The detection range of the tube for S^2- is 0.1¹0mg/L.更多还原
