Research on regulation of releasing concentration of selenium-supplement cup and its relative influential factors

摘要:
目的研究补硒杯释硒浓度的调控及其影响因素的关系。
方法筛选补硒剂配方, 药和械结合调节硒浓度(械: 能节制硒浓度的小容器)及械适宜孔径及合适药量选择。
结果在水温20~100℃, 浊度3~5度, pH65~85和水中常见阴阳离子在国家饮水卫生标准范围内, 水中硒浓度可控制在30~46μg/L。
结论经水质检查, 补硒杯的滤后水, 符合国家饮用水卫生标准, 硒浓度符合国家矿泉水标准, 解决了补硒杯中硒元素的稳定释放问题。

Abstract:
Objective To research the regulation and influential factors of selenium-releasing concentration in selenium-supplement cup.
Methods To screen out the formula of selenium-supplement reagent, combine the reagent and instrument to adjust the concentration of selenium and search for the suitable radius of the instrument and select the appropriate dose of the reagent.
Results Under following circumstances, water temperature 20-100℃, turbidity 3-5 degree, pH 6.5-8.5, usual cations and anions in water in accordance with the state standard, the concentration of selenium in water is controlled within 30-46 μg/L.
Conclusion By checking out water quality, the filtering water supplement cup accords with the state drinking-water sanitary standard and the concentration of selenium tallies with the state mineral water criteria.
