The absorption-elutiontest using low ionic strength solution (LISS) has been compared with the test using normal saline in MN typing of 258 bloodstain samples stored 1 to 6 years.
The extensive test indicated that the resin selected was better for the extraction of gold by the resin-in-pulp process and that the elution conditions determined were suitable.
扩大试验的结果证明,本工作为树脂矿浆法提取金选择了较好的树脂,确定了较适宜的解吸方案及解吸条件。

MethodsThe orthogonal test was adopted to study the eluting effect of MDG with the elution rate as an index, and concentration of eluant, amount, elution velocity as the influence factors.
