The fluorescence spectrometry and calcium carbonate deposition method are adopted to evaluate the performance of the fluorescently-labeled compound water treatment reagent. As a result, there is a linear relationship between its fluorescence intensity and its concentration. The fluorescent tracer, with good fluorescence performance, has little effect on compound water treatment reagent. Meanwhile the temperature, time, pH are investigated to value the influence on the fluorescence intensity of the fluorescently-labeled compound water treatment reagent. As a result, the fluorescently-labeled compound water treatment reagent has good stability with little effect by the above situation. Therefore, the content of compound water treatment reagent in water treatment system can be calculated by the fluorescence intensity of fluorescent tracer, so as to quantitively control the effective concentration of compound water treatment reagent in water treatment system,%通过荧光光谱法和碳酸钙沉积法研究了荧光标记复配水处理剂的性能并进行了评价.试验表明,该荧光标记复配水处理剂的荧光强度与其质量浓度呈良好的线性关系,且荧光示踪剂对复配水处理剂的阻垢性能基本没有影响.同对考寨了温度、时间、pH等因素对荧光标记复配水处理剂荧光强度的影响.结果表明,荧光标记复配水处理剂的稳定性良好,受上述情况的影响较小,因此通过对荧光标记复配水处理剂的荧光强度分析可以确定水处理系统内复配水处理剂的含量.将荧光发射值与此复配水处理剂的浓度关联起来,从而定量地控制循环冷却水中复配水处理剂的有效浓度.
