摘要
样品用Na2 O2 -Na2 CO3 在 70 0℃用镍坩锅熔溶 ,稀硫酸提取 ,2 0 0目玻璃砂芯漏斗过滤 ,不溶物再用H2 SO4 -H3 PO4 加热溶解 ,把滤液和溶解并入 5 0 0ml容量瓶中定容 ,进行全分析 ,用此方法溶样完全 ,分析速度提高。
sm1p1e ore with Na 2O 2-Na 2CO 3 has be mo1ten at 700℃ by nickel crucible,the compound is dissolved by thin H 2SO 4,and solution is fi1tered through by a glass filter press 200holes/mm 2.The remained is heating dissolved again with H 2SO 4-H 3PO 4,a11 the filtrate and solution are transferred into 500ml vessel,and is analyzed completely.Sample ore can be dissolved completely,and analyses speed be improved.
