| 摘 要： | 硅锰合金试样中低含量铝的测定，常用的方法灵敏度较低，本方法利用硝酸，氢氟酸分解，高氯酸冒烟，1＋1盐酸浸取，加入氢氧化钠强碱分离锰，铁，铜，钛等干扰元素，调节酸度pH=5．6，在六次甲基四铵缓冲的条件下，使铝和铬天青S生成紫红色配合物，在波长560nm处测其吸光度，借此测定铝，灵敏度提高，方法简便稳定。

| Abstract: | In the determination of Al in silico-manganese,the interference elements were separated with sodium hydroxide,and the 1+1 hydrochloric acid was used as leaching agent.At the presence of buffer agent and pH=5.6,the Al in silico-manganese reacted with chrome azurol S to form a complex.The absorbance of the complex was determined at 560nm.After that,the Al in silico-manganese was determined. |
