The historical version replaced by this Part is as follows. - GB/T 11064.3-1989. Methods for chemical analysis of lithium carbonate, lithium hydroxide monohydrate and lithium chloride - Part 3.Determination of lithium chloride content - Potentiometric method1 ScopeThis Part of GB/T 11064 specifies the determination method for lithium chloride content in lithium chloride. This Part applies to the determination of lithium chloride content in lithium chloride. The determination range. more than 95.00%.2 Method summaryThe sample is dissolved in water. In acidic solution, use silver (or silver-silver sulfide) electrode as measuring electrode; use calomel electrode as reference electrode; and use silver nitrate standard solution to titrate chloride. Use secondary derivative to determine the reaction end; use the consumed amount of silver nitrate standard titration solution to calculate the content of lithium chloride.3 ReagentsUnless otherwise indicated, all reagents used in this Part are analytical reagent, the water used is deionized water. 3.1 Nitrate (1+1), guarantee reagent. 3.2 Bromophenol blue ethanol solution (1g/L). 3.4 Silver nitrate standard titration solution [c(AgNO3) = 0.1000mol/L]. 3.4.1 Preparation. Weigh 17.0g of silver nitrate; place them in a 250mL beaker; add 50mL of water to dissolve; transfer to a 1000mL brown volumetric flask; dilute with water to scale; mix well. 3.4.2 Calibration. Calibration shall be done with sample determination in parallel. Weigh three-portions 25.00mL of sodium chloride standard solution (3.3); place them in 250mL beakers respectively; add water to 150mL; add a drop of bromophenol blue ethanol solution (3.2); add 1 drop ~ 2 drops of nitrate (3.1) until the solution turns to yellow; place electromagnetic stirring bars; place the beakers on an electromagnetic stirrer; 3.4.3 The actual concentration of silver nitrate standard titration solution shall be calculated according to equation (2).4 Instruments4.1 Potentiometer. the accuracy is 2mV. 4.2 Measuring electrode. silver electrode or silver-silver sulfide electrode.5 SamplesSamples shall be baked in advance at 250°C ~ 260°C for 2h, and placed in the dryer to cool to room temperature.6 Analysis steps6.1 Samples Weigh 4g ~ 5g of samples; place them in a weighting flask, which has been weighed to constant weight and baked in advance at 250°C ~ 260°C for 2h; bake it at 250°C ~ 260°C for 2h; place it in the dryer to cool to room temperature. Weigh it, accurate to 0.0001g. The difference between two masses is the mass of the sample. 6.2 Number of determination Independently carry out two measurements; take the mean value. 6.3 Blank test Conduct blank test along with the sample. 6.4 Determination7 Calculation of analysis resultsContent of lithium chloride is calculated in mass fraction wLiCl of lithium chloride, expressed in %, according to equation (3).8 Precision8.1 Repeatability For the two independent test results obtained under repeatability conditions, within the average-value range as given below, the absolute difference of these two test results does not exceed the repeatability limit (r), and the situation exceeding repeatability limit (r) is not more than 5%. Repeatability limit (r), according to Table 1, adopts linear interpolation to obtain.9 Test reportThe test report shall contain the following content. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
