摘要

再生水中磷绝大部分为无机磷，是引起循环冷却系统结垢腐蚀的重要因素。为了探究无机磷在系统内的迁移转化及其对系统的影响，无机磷的定量定性尤为重要。在分析了无机磷的SMT( standard measurements and testing)连续提取法在循环冷却系统污垢提取中应用的可行性的基础上，对SMT提取方法进行条件优化，建立了污垢中无机磷定性定量分析方法。结果表明，优化后的SMT连续提取法能够实现对系统内污垢中无机磷的完全提取，且回收率接近100%；污垢中弱吸附态磷（NH

Cl-P）、铝结合态磷（Al-P）、铁结合态磷（Fe-P）和钙结合态磷（Ca-P）4种形态无机磷能得到完全分离。

Abstract

Most of the phosphorus in the reclaimed water is inorganic phosphorus

which is an important factor causing scale corrosion of the circulating cooling system. To explore the migration and transformation of inorganic phosphorus in the system and its influence on the system

the quantitative determination of inorganic phosphorus is particularly important. The feasibility of SMT continuous extraction

of inorganic phosphorus in the fouling of the circulating cooling system was carried out

the inorganic phosphorus SMT was optimized and improved

and a qualitative and quantitative analysis method for inorganic phosphorus was established. The results showed that the majorization of SMT extraction method was able to extract the inorganic phosphorus in the scale completely

the recovery rate was close to 100%， and weakly adsorbed phosphorus (NH

Cl-P)

aluminum-bound phosphorus (Al-P)

iron-bound phosphorus (Fe-P) and calcium-bound phosphorus (Ca-P) in the scale can be completely separated.
