离子选择电极法测定土壤中氟前处理的改进初探

摘要

用离子选择电极法测定土壤中的氟的前处理过程中，将使用标准步骤与省略在电炉上加热至近沸这一步骤进行对比实验并进行数理统计，结果表明省略在电炉上加热至近沸这一步骤更为简便和安全%　　Theexperimentisconductedtocomparethetwostepsduringtheprocessofthepretreatmentfordetecting thefluorideinsoilbyionselectiveelectrode.Oneisjustthestandardstep,whilethereisnoheatingonanelectric stovetoboilingintheotherstep.Themathematicalstatisticsshowthattheomissionofheatingmakesthepretreat-mentsimpleandsafe.
