Chinese Abstract

採用原子吸收分光光度法分析了不同濃度海水灌溉的3年生庫拉索蘆薈中Ca、Mg、Na、K、Mn、Zn、Fe、Cu、Ni、Pb、Cd、Cr共12種微量元素的含量。試驗發現:各元素在蘆薈中的含量差異較大,其中,Ca、Mg、Na、K含量豐富,Mn、Zn、Fe含量中等,而有毒重金屬離子Cu、Ni、Pb、Cd、Cr含量很低;無論是凝膠還是全葉中,海水濃度對庫拉索蘆薈中Ca、Mn元素的影響很大,對其他各種元素的影響不大,但Cd離子的含量隨海水灌溉濃度的昇高呈略微上昇趨勢。

English Abstract

Twelve trace elements including calcium, potassium, magnesium, sodium, manganese, zinc, iron, copper, lead, nickel, cadmium and chrome in Aloe barbadensis Mill were determined by flame atomic aborsorption spectrometry. The aloe has been irrigated for three years with seawater of different concentrations. Results indicated that the content of the twelve kind elements was different. The content of calcium, potassium, magnesium, sodium was high; the content of manganese, zinc and iron was medium; and the content of copper, lead, nickel, cadmium and chrome was low in Aloe barbadensis Mill. The concentration of seawater had great influence on the content of calcium and manganese, while this influence was minor on other elements. A slight increase of cadmium in gel and whole leaf of Aloe barbadensis Mill was observed with higher seawater concentration.
