氨基磺酸的质量检测方面应该注意什么?
来源:http://www.jnjrh.com 日期:2019-09-30 发布人:admin
氨基磺酸水溶液可去除铁、钢、铜、不锈钢等资料制造的设备外表的水垢和腐蚀产物。另外,它还是独一可用作镀锌金属外表清洗的酸。
Aminosulfonic acid aqueous solution can remove scale and corrosion products on the surface of equipment made of iron, steel, copper and stainless steel. In addition, it is the only acid that can be used for cleaning the surface of galvanized metal.
氨基磺酸质量规范和检测办法
Quality Specification and Detection Method of Aminosulfonic Acid
1、外观:用肉眼察看,如是白色斜方晶系.片状结晶则为合格,否则为不合格。
1. Appearance: When viewed with naked eyes, if it is a white orthorhombic system, flaky crystals are qualified, otherwise they are unqualified.
2、含量:称取2.5g样品,准确至0.00移入250mL锥形瓶中,参加100ml蒸馏水,待溶解后,加2~3滴1%盼酞指示剂,用1mo1/L氢氧化钠规范溶液滴定至溶液呈粉红色,坚持3nin。记下此时耗费的体积V。同时做空白实验。
2. Content: Take 2.5G sample and transfer it into 250 mL conical bottle accurately to 0.00. Participate in 100 ml distilled water. After dissolution, add 2-3 drops of 1% phthalocyanine indicator, titrate with 1mo1/L sodium hydroxide standard solution until the solution is pink, stick to 3nin. Write down the volume V consumed at this time. At the same time, blank experiments were done.
氮基磺酸(%)=(V-V0)XCX97.09X 100/1000X mu
Nitrosulfonic acid (%)= (V-V0) XCX97.09X 100/1000X Mu
式中:v-一耗费氢氧.化钠规范溶液体积毫升数:m
Formula: V - consumption of hydrogen and oxygen. Sodium carbide standard solution volume milliliter: M
V0一-空白实验耗费氢氧化钠规范溶液的体积,mL
氨基磺酸
V0-1-blank experiment consumes sodium hydroxide standard solution volume, mL
C-氢氧化钠溶液规范的摩尔浓度:mol/L
Molar Concentration of C-Sodium Hydroxide Solution Specification: mol/L
97.09--氨基磺酸的摩尔质量;g/mol
97.09 - Molar mass of aminosulfonic acid; g/mol

因本公司实验室检测仪器设各有限,不能检测此样品,特采用供给商送货时附送产质量检验报告单上检验数据,与原资料检验规范对照,假如契合检验规范,则视为合格,若不契合则视为不合格。
Because our laboratory testing instruments are limited, we can't test this sample. We use the inspection data on the quality inspection report attached to the supplier when delivering the goods. It is compared with the original data inspection standard. If it conforms to the inspection standard, it will be regarded as qualified. If it does not conform, it will be regarded as unqualified.
