摘要：

A micro-extraction technique combined with GC/NPD was developed in order to estimate relative mobility of seven co-applied pesticides (alachlor, atrazine, carbofuran, cyanazine, ethoprop, metolachlor, and metribuzin) on soil TLC plates. A comparative study with C-14-labeled pesticides and autoradiography showed good agreement between the two techniques for determining the frontal or center R(f) values on a silty clay soil. The results also showed that mobility of any one pesticide was not affected by the presence of the other co-applied chemicals.
