酸化硫化物吹气装置:碱金属硫化物和硫化铵易溶于水,由于水解其溶液显碱性。碱土金属、钪、钇和镧系元素的硫化物较为难溶。当阳离子的外层电子构型为18电子和18+2电子时,往往由于较强的化作用而形成难溶的、有颜色的硫化物。大多数不溶于水的硫化物可溶于酸并释放出硫化氢,难溶的少数金属硫化物(如CuS、HgS)可用氧化性酸将其溶解,此时S被氧化成硫而从溶液中析出。难溶金属硫化物在溶液中存在以下溶解-沉淀平衡:式中M为金属。控制溶液的酸度,可以改变溶液中S离子的浓度,从而将溶解度各不相同的难溶金属硫化物分别沉淀出来。这是定性分析中用硫化氢分离、鉴定金属离子的基础

公司介绍
Generally think of pathogenic microorganisms in the wastewater are bacteria, viruses, rickettsia, protozoa and fungi, such as five, rickettsia between bacteria and viruses, some microbiologist, reduce pathogenic leptospira that representative body for syphilis for 6 kinds of pathogenic microorganism, and helix between bacteria and protozoa. Some microbes higher than protozoa, such as nematodes, can also cause disease. Domestic sewage and slaughtering, biological products, hospitals, tanning, washing hair and other industrial wastewater often contain these pathogenic microorganisms that can spread a variety of diseases
