摘要
本法叙述一氧化二氮－乙炔火焰原子吸收光度法测定铌量，用鞣酸沉淀分离和在盐酸－氢氟酸介质中加入增感剂三氯化铝。灵敏度１２μｇ／ｍＬ／１％吸收，检出限６．０μｇ／ｍＬ。
Describes a N_2O-C_2H_2 flame atomic absorption spectrometry for the determination of niobium content with tannic acid precipitationseparation and enhancement effect agent AlCl_3 solution added to the HCl-HF matrix solution.The sensitivity is 12μg/mL 1% absorption,the detection limit is 6μg/mL.
