碱渣中二价硫及硫醇的测定(硝酸银电位法)

在石油炼制过程中产生的碱渣污水,成份复杂,氧化性、还原性及重金属等其他干扰性物质复杂而难以确定,测定二价硫及硫醇时,用常规的方法去除干扰再用碘量法或比色法分析难以进行。采用电位滴定法,可以有效地测定碱渣中的二价硫和硫醇,并且通过大量的实验,找出了适合测定我公司石油炼制中产生的碱渣污水中二价硫和硫醇的特有规律。

Deterinination of bivalent sulfur and mercaptan in basic residue

complicated component and interferential substance that were too complicated to make certain such as oxidation、 deoxidation、 heavy metal and so in basic residue sewage from petroleum refining process make the determination of bivalent sulfur and mercapan hard to be completed by general method-determining by iodin measure or colormetry after wiping off oxidation and deoxidation substance. potentiometric titration method can determine bivalent sulfur and mercaptan effectively, the proper project for determining bivalent sulfur and mercaptan in basic residue from our company refining process was find out by completing large numbers of experiment.
