Theresults indicated that the initial desorption rate of As was higher than As, but thefinal desorption percentage of As was two times higher than As; that in therange of pH(6.5-8.5), the desorption of As was the lowest（pH=6.5）,and thepercentage increased with the pH value increasing or deescalating, but for the As,thepercentage increased with the increase of pH; that the supersonic accelerated desoptionof arsenic and the final percentage was lower than non-supersonic; that on the conditionof UV-light ,in a word, it took negative effect to desorption The"reproduced process"has been used in the procedure of regeneration.

实验结果表明，初始阶段，三价砷的脱附率高于五价砷，但最终脱附率三价砷低于五价砷；三价砷、五价砷在不同温度下的脱附实验表明三价砷的最佳脱附温度低于五价砷的最佳脱附温度；在pH=5.5-8.5时，随着pH的增大，五价砷的脱附率具有先减小再增大的趋势，在pH为6.5时脱附率降至最小；在pH=5.5-8.5时，三价砷的脱附率随pH的增大而增大；不论是三价砷还是五价砷的脱附过程，超声波条件都会促进脱附速率(来源：ecABC论a4文网www.abclunwen.com)的增加，并且最终的脱附率要高于无超声波条件下的脱附率；紫外光照条件下，随着光照时间的增加，两种价态砷的脱附率会达到一个较高的值，再降低。总体而言，紫外光照的存在不利于脱附的进行。

While arsenic-resisted strain can be filtrated from tame soil, it can provide theoretical basis for the bioremediation technology.

Methods Soil was air-dried, grinded, and screened through 100 mesh sieve. Appropriate sample was put in porcelain crucible with 0.5 g Aldrin reagents, and another 2 g Aldrin was used to cover the sample. Then the mixture was burned, cooled off, lixiviated by water, and determined by arsenic-cerium redox spectrophotometry.

土壤经自然风干，粉碎过100目筛，取适量试样于盛有0.5g艾氏试剂的瓷钳埚中，再取2g艾氏试剂覆盖试样，置高温炉中灼烧，冷却，水浸提，砷铈氧化还原分光光度法测定碘含量。
