一、前言根据不溶解的悬浮微粒所产生的混浊度来进行物质的定量测定的方法称为浊度测定法。由于浊度测定法操作简单、灵敏度高,因此得到了广泛的应用,磷、氨、钙、氯、硫、硫酸盐、氟化物、脂肪、蛋白质、淀粉酶等类物质均可用该法测定。此外,还可用于细菌和血球计数、血中卵磷脂和血红朊的临床测定,以及用于研究过滤、絮凝、沉淀、空气污染、颗粒尺寸分级等。近来,由于实现了浊度自动连续测定,因此国外已在酿酒、食品、水处理、制药、化工、造纸、制糖等工业部门用浊度自动检测装置来控制和调节生产过程。如
I. INTRODUCTION The method for quantitative determination of substances based on the turbidity produced by undissolved aerosols is called turbidimetry. Due to its simple operation and high sensitivity, the turbidimetric method has been widely used. The method can be used to determine phosphorus, ammonia, calcium, chlorine, sulfur, sulfate, fluoride, fat, protein and amylase. In addition, it can be used for bacterial and blood count, clinical determination of blood lecithin and hemoglobin, and for the study of filtration, flocculation, precipitation, air pollution, particle size grading. Recently, due to the realization of automatic continuous turbidity determination, foreign countries have been in the wine, food, water treatment, pharmaceutical, chemical, paper, sugar and other industrial sectors with automatic turbidity detection device to control and adjust the production process.
