利用自制设备对耐蚀材料(含 Ni40%,Fe28%,Cr20%,Mo10%)中,微量钙(0.0x%)的测试,其基体元素对测定均产生干扰,尤以镍影响最大。以铜试剂分离主体元素的方法,并加入氯化锶进行增感。在六个样品中,其回收率由76%～100%不等,而当滤液中镍量残留超过1毫克/毫升时有干扰。仪器测试条件为:波长422.7毫微米;狭缝10微米;灯电流3毫 The use of home-made equipment on the corrosion resistance of materials (including Ni40%, Fe28%, Cr20%, Mo10%), trace calcium (0.0x%) of the test, the matrix elements interfere with the determination, especially nickel most affected. The method of separating the main element with copper reagent and adding strontium chloride for sensitization. In six samples, the recoveries ranged from 76% to 100%, interfering with the amount of nickel remaining in the filtrate of more than 1 mg / ml. Instrument test conditions: wavelength 422.7 nm; slit 10 microns; lamp current 3 milliliters
