The Microamount Determination of Aluminium in Copper& alloys Using Fluoride Ion Selective Electrode 氟电极测定铜基合金中微量铝的研究
By the test for the base metals of carbon steels, stainless steels, copper and so on, the relationship between fluorine content in fluoride fluxes and spread ability for silver base filler metals has been discussed. 通过对碳钢、不锈钢和紫铜等母材进行试验,分析讨论了几种氟化物钎剂氟含量与银基钎料铺展性间的关系。
This method has been applied to the determination of microamount of copper in aluminum alloys with sodium fluoride as a masking agent. 采用氟化钠作掩蔽剂,可不经分离,直接测定铝合金中的微量铜。
Study on the Effects of Selenite on the Changes of Copper, Zinc and Iron in Serum, Kidney and Femur Induced by Fluoride in Rats 硒对氟致大鼠血清肾和股骨中铜锌铁影响的研究铁与细胞因子蠕墨铸铁的生产
Lead and zinc smelting wastewater is mainly characterized by low pH, high concentration of zinc, lead, copper, arsenic, fluoride and other impurities. Its component is complicated and treatment process is very difficult. 铅锌冶炼废水主要表现为低pH值,高浓度锌、铅、铜、砷、氟等杂质,成分复杂且处理困难。
