摘要
超微细白炭黑是一种具有活性的二氧化硅微粒,它与橡胶混炼时,显示出极高的补强效果和优异的物性,在乳胶、塑料薄膜、皮革、涂料、粘合剂、合成树脂、造纸、农药、炸药等方面也得到广泛利用。
The sample is treated with water, acid(hydrochloric acidor nitric acid)and hydrofluoric acid. Sodium content in carbon-whitehad been determinated using flame photometry and atomic absorption spec-trometry. Results show that the water treatment is low obviously, acidand hydrofluoric acid treatment is satisfactory. Besides, effect of determi-nation of sodium in the ordinary glass container storaged test solution isexamined.
