| 摘 要： | 利用KCl、NH4Ac、HCl、NaOH四种浸提液将沙棘叶中的铝浸提溶出,得到沙棘叶中铝的不同化学形态,采用分光光度法定量测定,测定结果:沙棘叶中的Al3+为10.7%,Al(OH)2+和Al(OH)+2为2.1%,胶态Al(OH)03为34.3%,有机铝为53.0%.浸提液中铝的回收率为86.9%～101.0%.

| Abstract: | Using four kinds of extraction solutions,i.e.,potassium chloride,ammonium acetate,hydrochloric acid,and sodium hydroxide solutions,the various chemical species of aluminum in Sea-buckthorn Leaf were obtained.The leaching aluminum species were determined with spectrophotometry,and the percentage distribution of aluminum species in the Sea-buckthorn leaf was calculated.The fraction of Al3+ in the total aluminum was 10.7%,Al(OH)2+ and Al(OH)+2 was 2.1%,Al(OH)03 was 34.3%,and the organic aluminum was 53.0%.The ... |
