Extensive soil sampling of the crop-reclaimed Mn mine wastelands was conducted in the six typical manganese minelands (Bayi, Lipu, Pingle, Quanzhou, Bansu and Xialei) in Guangxi, China. In the six reclaimed minesoils, the heavy metal concentrations were Pb 41.63~348.31 mgkg^(-1), Cr 48.12~287.29 mgkg^(-1), Zn 47.38~269.92 mgkg^(-1), Cu 12.71~138.03 mgkg^(-1), Cd 0.73~46.50 mgkg^(-1), and Mn 676.7~41996.4 mgkg^(-1) respectively.

The floatation rate of Pd (superscript 2+) reaches 100% when the concentrations of NaNO3, KBr and cetyl pyridinium bromide in solution are 0.05 g/mL, 3.0×10^(-2) mol/L, 5.0×10^(-4) mol/L(pH 4.0), respectively. Pd (superscript 2+) could be separated from Ru (superscript 3+), Al (superscript 3+), Cr (superscript 3+), Ni (superscript 2+), Ga (superscript 3+), Fe (superscript 3+) and Zn (superscript 2+) by floatation quantiatively. A method of flotation separation and enrichment of Pd (superscript 2+) was established.

当溶液中硝酸钠、溴化钾、溴化十六烷基吡啶的浓度分别为0.05 g/mL，3.0×10^(-2)mol/L，5.0×10^(-4)mol/L，在pH 4.0时，Pd(上标 2+)的浮选率达到100%，Pd(上标 2+)可与Ru(上标 3+)，Al(上标 3+)，Cr(上标 3+)，Ni(上标 2+)，Ga(上标 3+)，Fe(上标 3+)，Zn(上标 2+)定量分离，据此建立了浮选分离和富集Pd(上标 2+)的新方法。

Theresults showed that certainly licorice zinc can remit the toxic-side effect ofCa-DTPA in respect of rat's body weight,exterior appearance,ranal injuryand deficiency of necessary trace elements such as Zn,Mn,Cu;that thetoxic-side effects of Ca-DTPA actually are relative to losing some necessarrtrace element...

两组动物各有一半在给药期间每日口服0.6g 甘草锌。同时，还分别用甘草铵和 ZnSO_4做比较实验。结果表明甘草锌确能减轻 Ca-DTPA 对大鼠体重、外观、肾脏病变和微量元素含量的不良影响。比较实验的结果表明，Ca-DTPA 的毒副作用实际上是与微量元素 Zn的丢失相关，而甘草锌的缓解效果主要是通过补锌达到的。
