摘要
研究了用铝试剂、乙酸－乙酸铵缓冲溶液组成的体系以及光度法测定松脂中微量铝的条件，提出了一种灵敏度、选择性和稳定性较好的测定松脂中铝的方法。在０—５０μｇ／５０ｍＬ范围内服从比耳定律。
A simple,sensitive,selective and stable absorption photometric method for the determination of aluminum in rosin is presented in this paper,aluminium(Ⅲ) is reacted with aluminon in the presence of acetic acid ammonium acetate.Beer's law is obeyed in the range of 0—50μg/50mL.
