4 试验方法

4 test method

4.1 外观

4.1 appearance

在正常光线下目测。

Visual inspection in normal light.

4.2 有效氯含量测定

4.2 determination of effective chlorine content

4.2.1配制2mol/L硫酸溶液、10%碘化钾0.5淀粉溶液。配制并标定0.1mol/L硫代硫酸钠滴定液。

4.2.1 prepare 2mol / L sulfuric acid solution and 10% potassium iodide 0.5 starch solution. Prepare and calibrate 0.1mol/l sodium thiosulfate titration solution.

4.2.2精密称取1g（精确至0.001g）至烧杯中以蒸馏水溶解，转入100ml容量瓶中。称量杯及烧杯需用蒸馏水洗3次，洗液全部转入容量瓶。

4.2.2 accurately weigh 1g (accurate to 0.001g) into beaker and dissolve it with distilled water, then transfer it into 100ml volumetric flask. The weighing cup and beaker shall be washed with distilled water for three times, and all the washing liquid shall be transferred into the volumetric flask.

4.2.3向100ml碘量瓶中加2mol/L硫酸10ml和混匀的消毒剂稀释液10ml，此时，溶液出现棕色。盖上盖并振摇混匀后加蒸馏水数滴于碘量瓶缘，置暗处5min。打开盖，让盖缘蒸馏水流入瓶内。用硫代硫酸钠滴定液（装于25ml滴定管中）滴定游离碘，边滴边摇匀。待溶液呈淡黄色是加入0.5%淀粉溶液10滴，溶液立即变蓝色。继续滴定至蓝色消失，记录用去的硫代硫酸钠滴定液总量，并将滴定结果用空白试验校正。重复测3次，取3次平均值进行一下计算。

4.2.3 add 10ml of 2mol / L sulfuric acid and 10ml of mixed disinfectant diluent to 100ml iodine volumetric flask. At this time, the solution appears brown. Cover and shake well, add a few drops of distilled water to the edge of the iodine measuring bottle, and place in the dark for 5min. Open the lid and allow distilled water from the lid edge to flow into the bottle. Titrate the free iodine with sodium thiosulfate titrant (in 25ml buret), and shake it up while dropping. When the solution is light yellow, add 10 drops of 0.5% starch solution, and the solution immediately turns blue. Continue to titrate until the blue disappears, record the total amount of sodium thiosulfate titrant used, and calibrate the titration result with blank test. Repeat the test three times, take the average value of three times for calculation.

4.2.4因为1mol/L硫代硫酸钠滴定液1ml相当于0.03545g有效氯，故可按下式计算有效氯含量。

4.2.4 because 1ml of 1mol / L sodium thiosulfate titration solution is equivalent to 0.03545g of effective chlorine, the effective chlorine content can be calculated according to the following formula.

有效氯含量（g/100g）=c×Vst×0.03545÷m×100%---------(1)

Effective chlorine content (g / 100g) = C × VST × 0.03545 ÷ m × 100% ---- - (1)

c--------为硫代硫酸钠滴定液浓度（mol/L）；

C ------- concentration of sodium thiosulfate titration solution (mol / L);

Vst-----为滴定用去硫代硫酸钠滴定液毫升ml；

VST refers to ml of sodium hyposulfite titration solution for titration;

m-------为碘量瓶中所含消毒剂原药克数g；

M ------ g of the original disinfectant contained in the iodine measuring bottle;

V--------为电量瓶中含液体消毒剂原液毫升数ml。

V -------- ml of original liquid containing liquid disinfectant in electric quantity bottle.

4.3  PH值的测定

4.3 determination of pH value

按《中华人民共和国药典》2005版，附录VIIG   PH值规定的方法定法执行。

According to the method specified in Pharmacopoeia of the people's Republic of China, 2005 edition, appendix viig pH value.

4.4 水份含量的测定

4.4 determination of water content

按GB/T6284---1986中2.2的规定执行。

According to 2.2 of GB / t6284-1986.

4.5 溶解度的测定

4.5 determination of solubility

称取样品25克（精确至0.01g）置于250ml锥形瓶中，加入100ml蒸馏水，然后塞好橡皮塞，橡皮塞上分别插一支细玻璃管和一支温度计，放入25℃水浴锅中，保持恒温20min～30min,观察锥形瓶中样品是否完成溶解、清澈透明。若有乳状物或絮状物存在则达不到本标准要求。

Weigh 25g (accurate to 0.01g) of the sample and put it into a 250ml conical flask, add 100ml of distilled water, then plug the rubber stopper, insert a fine glass tube and a thermometer on the rubber stopper respectively, put them into a 25 ℃ water bath, keep the constant temperature for 20min-30min, and observe whether the sample in the conical flask is completely dissolved, clear and transparent. If there are emulsions or floccules, they cannot meet the requirements of this standard.

4.6 消毒效果测定            按卫生部《消毒技术规范》有关规定进行。

4.6 the disinfection effect shall be determined in accordance with the relevant provisions of the technical specifications for disinfection issued by the Ministry of health.

4.7 毒理安全性              按卫生部《消毒技术规范》有关规定进行。

4.7 the toxicological safety shall be carried out in accordance with the relevant provisions of the technical specifications for disinfection issued by the Ministry of health.
