| titleOfInvention | Method for detecting alkali liquor used in solar cell production process |
| abstract | The invention discloses a method for detecting an alkali liquor used in a solar cell production process, which is used for detecting the concentrations of sodium hydroxide and sodium silicate contained in the alkali liquor. The detection method comprises the following steps of: titrating the alkali liquor to be neutral with an acid, and detecting the concentration relation between the sodium hydroxide and the sodium silicate in the alkali liquor; adding excessive and quantitative sodium fluoride and hydrochloric acid into the treated alkali liquor, and inversely titrating residual hydrochloric acid with sodium hydroxide to detect the concentration of the sodium silicate in the alkali liquor to be tested; and calculating the concentration of the sodium hydroxide according to the obtained concentration relation between the sodium hydroxide and the sodium silicate. In the invention, component concentration in the alkali liquor is detected by using an inverse titration method, so that the method has the advantages of high accuracy, low cost, easiness in operating and low time consumption, and plays a role in well guiding and referring for industrial production. |
