含量分析

Content analysis

精确称取试样约1.5g，溶于40ml新煮沸并冷却后的水中，冷15℃，加酚酞试液(TS-167)数滴，用1mol/L硫酸滴定。在粉红色消失时，记录所耗的酸量，加甲基橙试液(TS-148)数滴，继续滴定呈现持续不褪的粉红色。记录滴定所需酸的总体积。每Ml1mol/L硫酸相当于总碱量(以KOH计)56.11mg。

Accurately weigh approximately 1.5g of the sample, dissolve it in 40ml of freshly boiled and cooled water, cool to 15 ℃, add a few drops of phenolphthalein test solution (TS-167), and titrate with 1mol/L sulfuric acid. When the pink color disappears, record the amount of acid consumed, add a few drops of methyl orange test solution (TS-148), and continue titrating until a persistent pink color appears. Record the total volume of acid required for titration. Each Ml1mol/L sulfuric acid is equivalent to 56.11mg of total alkali content (calculated as KOH).

使用

Use safety

对组织有烧灼作用，可溶解蛋白质，形成碱性变性蛋白质。溶液或粉尘溅到皮肤上，尤其溅到黏膜，可产生软痂。溶液浓度越高，温度越高，作用越强。溅入眼内，不仅可损伤角膜，而且能使眼部深组织损伤。

It has a burning effect on tissues and can dissolve proteins, forming alkaline denatured proteins. Solution or dust splashing on the skin, especially on the mucous membrane, can produce soft scabs. The higher the concentration and temperature of the solution, the stronger the effect. Splashing into the eye can not only damage the cornea, but also cause deep tissue damage to the eye.

高容许浓度为0.5mg/m。工作时应防止触及皮肤和眼睛，如不慎触及时，可用流水洗涤受损部位，然后湿敷5%的醋酸、酒石酸、盐酸或柠檬酸溶液；如溅人眼内，应用流水或生理盐水仔细缓慢洗涤10～30min，然后点入2%的奴佛卡因或0.5%的地卡因溶液。操作时应穿由结实布制作的工作服，戴橡皮手套、袖套、围裙，穿胶鞋等劳保用品，手上宜涂敷中性和疏水软膏。

The high allowable concentration is 0.5mg/m. During work, it is necessary to prevent contact with the skin and eyes. If accidentally touched in a timely manner, the damaged area can be washed with running water, and then wet applied with 5% acetic acid, tartaric acid, hydrochloric acid or citric acid solution; If splashing into the eyes, wash carefully and slowly with running water or physiological saline for 10 to 30 minutes, and then add 2% novocaine or 0.5% dicaine solution. During operation, work clothes made of sturdy cloth, rubber gloves, sleeves, aprons, rubber shoes and other labor protection equipment should be worn, and neutral and hydrophobic ointment should be applied to hands.
