含量分析

Content analysis

精確稱取試樣約1.5g，溶于40ml新煮沸并冷卻后的水中，冷15℃，加酚酞試液(TS-167)數(shù)滴，用1mol/L硫酸滴定。在粉紅色消失時，記錄所耗的酸量，加甲基橙試液(TS-148)數(shù)滴，繼續(xù)滴定呈現(xiàn)持續(xù)不褪的粉紅色。記錄滴定所需酸的總體積。每Ml1mol/L硫酸相當(dāng)于總堿量(以KOH計)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

對組織有燒灼作用，可溶解蛋白質(zhì)，形成堿性變性蛋白質(zhì)。溶液或粉塵濺到皮膚上，尤其濺到黏膜，可產(chǎn)生軟痂。溶液濃度越高，溫度越高，作用越強(qiáng)。濺入眼內(nèi)，不僅可損傷角膜，而且能使眼部深組織損傷。

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.

高容許濃度為0.5mg/m。工作時應(yīng)防止觸及皮膚和眼睛，如不慎觸及時，可用流水洗滌受損部位，然后濕敷5%的醋酸、酒石酸、鹽酸或檸檬酸溶液；如濺人眼內(nèi)，應(yīng)用流水或生理鹽水仔細(xì)緩慢洗滌10～30min，然后點(diǎn)入2%的奴佛卡因或0.5%的地卡因溶液。操作時應(yīng)穿由結(jié)實布制作的工作服，戴橡皮手套、袖套、圍裙，穿膠鞋等勞保用品，手上宜涂敷中性和疏水軟膏。

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.
