Introduction to lanthanum chloride:
Barium chloride is a white crystal, easily soluble in water, slightly soluble in hydrochloric acid and nitric acid, insoluble in ethanol and ether, easy to absorb moisture, and needs to be sealed and stored. As an analytical reagent, a dehydrating agent, a bismuth salt, and used in electronics, instrumentation, metallurgy and other industries.
The main purpose:
Mainly used for metal heat treatment, strontium salt manufacturing, electronic instrumentation, also used as heat treatment agent in mechanical processing. Determination of sulfate and selenate, chromatographic analysis, spot analysis of platinum, water softener. Fabric dyeing.
Storage and transportation conditions:
Store in a cool, ventilated warehouse. Keep away from fire and heat. The package is sealed. It should be stored separately from oxidants, acids and food chemicals, and should not be mixed.
Risk:
Ingestion of 0.2 to 0.5 g of barium chloride can cause poisoning, and the lethal dose is 0.8-0.9 g. If you find poisoning, take magnesium sulfate or sodium sulfate, take gastric lavage, enema, vomiting and other measures. Seek medical attention quickly, sputum poisoning has obvious symptoms of hypokalemia. The LD50 is about 118 mg/kg.
