Procedure for Sulphate Analysis:– Take 100 ml of water sample in a clean beaker. Add to it 40-50 ml of benzidine hydrochloric solution ( prepared hy disolving 4g of benzidine base in 10 ml of con.HCl ; and then diluting the solution to 1 litre with distilled water). Mix throughly giv...
sulphate analysisA new flow-injection analysis (FIA) system with detection by an electrode-separated piezoelectric quartz crystal (ESPQC) was developed for sulphate determination in water. The method was based on the decrease in conductivity upon precipitation of barium sulphate due to the mixing ...
1. 硫酸盐:硫化氢系植物(vegetation)、土壤、死水(stagnant water)及动物排泄物中的硫酸盐(sulphate)经细菌分解后演变而来. 在大气中,它很容易被氧化成二氧化硫且经雨水带至地面. 在某些好氧性(aerobic)土壤中,特定的细菌将二氧化硫转换成硫酸盐. 2. 硫酸化合物硫酸盐:sullagebarge 垃圾驳 | sulphate 硫酸化合物...
