摘　　要：采用可见分光光度法测定植物中的钼。该法在 0 .1 0～ 1 .5 μg mL钼的浓度范围内符合比耳定律 ,回收率为 95 .2 %～ 1 0 2 % ,相对标准偏差 (RSD)为 0 .5 4 %～ 3 .1 6% ,摩尔吸光系数为 5 .7× 1 0 4L·moL- 1 ·cm- 1 。该方法灵敏度高 。A new method for the determination of Molybdenum content in plants by extraction Spectrphotometry was introduced. The linear range and correlation coefficient of linearity for the method were 0.1～1.5 ug/ml and 0.993.respectivety.The recoveries of the method were 95.2 %～102 %,while RSDs are 0.54 %～3.16 %. molar absorptirity was 5.7×10 4 lmol -1cm -1. The method was simple, rapid and accurate.
