methods the liquid chloridion reagent was lyophilized for the preparation of reagent in powder form, which was then sealed into a detector cup of micro spectrometer for later experiment.
the experiment condition to determine chloridion in cement and clinker with spectrophotography, using polyvinyl alcohol as protective colloid, was studied.
研究了以聚乙烯醇作保护胶体 ,用分光光度法测定水泥及熟料中氯离子的实验条件。
because calcium ion content is significantly higher than others, calcium salt becomes main harm ion. chloridion enrichment is significant than sulphate ion in rhizosphere.
硫酸根离子在根际和非根际土壤均显着高于氯离子,说明该地区土壤以硫酸盐类为主;
chloridion participated in various kinds of biological function, such as cellular immunologic response , cell migration, cellular proliferation and differentiation, apoptosis.
