• SCR直接光度法测定镁合金中微量铍

  来源： 《材料工程2002年第12期》——刘众宣

  SCR直接光度法测定镁合金中微量铍 刘众宣1 (1.哈尔滨东安发动机(集团)有限公司,哈尔滨,150066) 摘要:在pH=9.6的溶液中, 以乙二胺四乙酸二钠(EDTA)和酒石酸钠为掩蔽剂,铍(Be)与铬天青R(SCR),溴化十六烷基三甲基胺(CTMAB)形成三元络合物.在波长 558nm 处有最大吸收, 摩尔吸收系数ε为3.06×104 L*mol-1*cm-1 ,铍量在0~5.00μg/100mL范围内,服从比耳定律,方法准确,可靠,有很好的选择性.适用范围为含铍0.0005%~0.0050%.样品回收率可达100%,适用于镁合金中微量铍的测定. 关键词:SCR; 直接光度法; 镁合金; 微量铍; [全文内容正在添加中] ......
