3 Method summary

Sample decomposition with hydrochloric acid, filtered, and the residue was neutralized with sodium carbonate - potassium carbonate - boric acid flux melt, dilute hydrochloric acid leaching, combined with the main solution was evaporated Salt to the wet form. In concentrated hydrochloric acid was added to make silicone glue cohesion, filtered silicon molybdenum blue spectrophotometric determination of silicon dioxide filtrate the amount. After precipitation with hydrochloric acid burning - in addition to boron ethanol, and then calcined to constant weight. With hydrofluoric acid, sulfuric acid treatment, the silicon to form silicon tetrafluoride Plaza, burning to Constant, the reduction in the amount of silica and the filtrate is the sum of the content of silica.
