污水中硫化物的分析有比色法与容量分析法等。由于污水本身的颜色、混浊与存在各种复杂成份,使比色法与容量分析法在操作过程中带来困难,或因严重干扰而不适用。离子选择电极是1966年以后蓬勃发展起来的一门电化学分析新学科。硫离子选择电极测定制革污水中硫化物,并不受污水的颜色、混浊、栲胶、油酯、蛋白质与各种有机 Sewage sulfide in the analysis of colorimetric and capacity analysis method. Due to the color, turbidity and presence of various complex components of the wastewater itself, colorimetric and volumetric methods are difficult to operate or not suitable for serious disturbances. Ion selective electrode is a new discipline of electrochemical analysis that flourished after 1966. Sulfide selective electrode for the determination of sulphide in tannery effluents is not affected by the color, turbidity, sebum, oil esters, proteins and various organic
