硒酸钠 制备方法及用途

制备方法

1.可由硒酸与氢化钠作用而制得。2.生成硒酸钠的反应方程式有.将亚硒酸钠在空气中于700~725℃加热,亚硒酸钠即转化为硒酸钠。另外将准确称量的干燥的碳酸钠与二氧化硒按等物质量混合,或者用干燥的碳酸钠与元素硒按等物质量混合,在空气中慢慢加热这种混合物使温度升到700~725℃也可制得硒酸钠。3.用硒酸与碳酸钠反应即可制得硒酸钠.将125g Na2CO3分次慢慢地加入到含181g H2SeO4的溶液中,碳酸钠溶解完之后(必要时过滤),将所得的溶液尽量加热浓缩,直至有相当大量的沉淀生成。若此时出现微弱的红色或棕色(由于溶解的胶体硒所致),则应再用水稀释,煮沸并放置1~2h后过滤。随后再蒸发。趁热吸滤,使Na2SeO4晶体在温度不低于45℃的情况下与母液分离。将结晶夹在两层滤纸中间挤压使其干燥。

SECTION 3 - HAZARDS IDENTIFICATION EMERGENCY OVERVIEW Toxic by inhalation and if swallowed. Danger of cumulative effects. Very toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. Potential Health Effects
Eye:
Causes severe eye irritation.
Skin:
Causes skin irritation. May be absorbed through the skin in harmful amounts. Chronic exposure to selenium may cause central nervous system effects, digestive tract disturbances, pallor, garlic breath,
Ingestion:
May be fatal if swallowed. Poison by ingestion. Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause liver and kidney damage. May cause cardiac abnormalities.
Inhalation:
Causes respiratory tract irritation. Irritation may lead to chemical pneumonitis and pulmonary edema. Inhalation of fumes may cause metal fume fever, which is characterized by flu-like symptoms with metallic taste, fever, chills, cough, weakness, chest pain, muscle pain and increased white blood cell count.
Chronic:
May cause reproductive and fetal effects. Chronic exposure to selenium may cause central nervous system effects, digestive tract disturbances, pallor, garlic breath, Laboratory experiments have resulted in mutagenic effects.
SECTION 4 - FIRST AID MEASURES
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Notes to Physician:


SECTION 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.

Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation.
Storage:
Store in a cool, dry place. Keep container closed when not in use.
SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.

Skin:
Wear appropriate gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize contact with skin.
Respirators:
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.
