Supply of potassium silicate Potassium silicate _ quote _ plain clay

Some time ago Beijing teachers and Industry, Department of Chemistry and Environmental Engineering at the University of bold ideas, put forward by flame atomic absorption spectrometry pure sodium (potassium) in water glass method of trace elements calcium and aluminum. Now I am going to tell us something about this new detection methods, as follows: HF-HClO_4 sample digestion, was measured by a standard curve method, the method is a good linear calibration curve, the correlation coefficient was 0.999, the linear range of Ca: 0 ~ 4μg / mL, Al: 0 ~ 10μg / mL. Recoveries were 100% ~ 105% (Ca) and 90% ~ 103% (Al), coefficients of variation were 1.7% ~ 5.2% (Ca) and 6.8% ~ 9.5% (Al). Applied to the actual sample analysis method is rapid, simple, good reproducibility and accuracy. You may have never heard of potassium silicate, but you must have heard it called "sodium silicate." Next to me to you briefly the basic case of potassium silicate. Potassium silicate is formed of a soluble silicate containing different proportions of alkali metal and silica system composed generally contain water. Common water glass into sodium water glass and potassium silicate, also relatively rare for the quarter, according to Keng glass and water glass.
