氢氧化锆共沉法与目前常见的分析法比较,具有操作简便,对操作者的健康无危害,不产生有害废弃物等优点,是比较理想的处理方法。用本共沉法测定海水中的微量重金属以前虽进行过研究,而应用于食品分析方面的实例却较少。天川等报导了用本共沉法定量清凉饮料水中的锡和铅。在以前的报告中,著者等应用本共沉法定量高盐食 Compared with the common analytical methods, zirconium hydroxide co-precipitation method has the advantages of simple operation, no harm to the health of operators and no harmful waste, which is an ideal treatment method. Although there are few studies on the determination of trace heavy metals in seawater using the coprecipitation method, few are applied to food analysis. Tetsugawa et al. Reported on the quantification of tin and lead in cool drinkable water using this co-precipitation method. In previous reports, authors and others applied the co-precipitation method to quantify high salinity foods
