氢氧化钾生产过程中的质量指标您知道包含什么要点吗？虽然我们在生活中可能不会常使用过，但一些事项可以来了解一番，比如这个问题，下面氢氧化钾厂家为您讲解。

Do you know the key points of the quality indicators in the production process of potassium hydroxide? Although we may not use it often in our life, we can learn something about it. For example, the potassium hydroxide manufacturer will explain this problem to you.

1．碳酸盐：在含量分析中介于酚酞和甲基橙终点之间所耗的每mL1mol/L硫酸，相当于碳酸钾138.2mg。

1. Carbonate: every mL1mol/L of sulfuric acid consumed between the end points of phenolphthalein and methyl orange in content analysis is equivalent to 138.2mg of potassium carbonate.

2．重金属：取试样670mg，溶于5ml水和5ml稀盐酸试液(TS-117)的混合液中。加热沸，冷却，用水稀释25ml，后过滤。以此作为试样液，按GT-16方法测定。用含20μg铅离子的对照液(溶液A)。

2. Heavy metals: take 670mg sample and dissolve it in 5ml water and 5ml dilute hydrochloric acid test solution (TS-117). Heat to boiling, cool, dilute with water to 25ml, and filter. Take this as the sample solution, and determine according to GT-16 method. 20 for use μ G Reference solution of lead ion (solution A).

3．水不溶物：5%试样水溶液应无色透明。

3. Water insoluble matter: 5% sample water solution shall be colorless and transparent.

4．铅：取试样1g溶于5ml水和11ml稀盐酸试液的混合液中，冷却。以此作为试样液按GT-18方法测定。对照液中的铅离子量取10μg。

4. Lead: Dissolve 1g of the sample in 5ml water and 11ml dilute hydrochloric acid test solution, and cool it. Take this as the sample solution and determine according to GT-18 method. The amount of lead ion in the control solution is 10 μ g。

5．汞：按CT-22方法测定。标准液和试样液按如下方法制备。

5. Mercury: determined according to CT-22 method. The standard solution and sample solution shall be prepared as follows.

(1)标准液的制备：按GT-22制各贮液和稀释液，使所得溶液每ml中含汞1μg。取该溶液1ml，放入－50ml烧杯，加水20ml、1:4稀硫酸溶液1ml和4%高锰酸钾溶液1ml。用表面皿盖住烧杯，煮沸数秒钟后冷却，备用。

(1) Preparation of standard solution: prepare each storage solution and diluent according to GT-22, so that each ml of the obtained solution contains 1 mercury μ g。 Take 1ml of the solution, put it into a - 50ml beaker, and add 20ml of water, 1ml of 1:4 dilute sulfuric acid solution and 1ml of 4% potassium permanganate solution. Cover the beaker with a watch glass, boil it for a few seconds, and then cool it for standby.

(2)试样液的制备：取试样10.0g放入－100ml烧杯，加水15ml使之溶解，加酚酞试液(TS-167)2滴，在不断搅拌下用1:1稀盐酸溶液缓慢中和。加1:稀硫酸溶液1ml和4%高锰酸钾溶液1ml，用表面皿盖住烧杯，煮沸数秒钟后冷却，备用。

(2) Preparation of sample solution: put 10.0g of sample into a 100ml beaker, add 15ml of water to dissolve it, add 2 drops of phenolphthalein test solution (TS-167), and slowly neutralize it with 1:1 dilute hydrochloric acid solution under constant stirring. Add 1ml of 1: dilute sulfuric acid solution and 1ml of 4% potassium permanganate solution, cover the beaker with a watch glass, boil for a few seconds, and then cool down for standby.
