摘要
将银离子固定在一种具有骨架结构的分子筛中,利用碘化银电离度极低特性,将生成的碘化银沉淀滞留在分子筛中。为避免金属离子带来的污染,样品再经过一种强酸性阳离子交换树脂,对金属离子进行脱除。
Put silver ions into molecular sieve with one kind of framework structure,they can react with iodine to form silver iodide,sedimentated in molecular sieve due to extremely low ionization.To avoid pollution caused by metal ions,the filter of cation exchange resin with strong acidity is needed to remove the ions in samples.
