| Abstract: | After digestion of effective Mo in soil through oxalic acid-ammonia oxalate solution（Tamm solution）,filtering,drying of filtrate by distillation,high-temperature ashing in muffle furnace,and extration by hydrochloric acid,effective Mo in soil is determined by inductance coupling plasma atomic emmission spectrum.The detection limit（3s） is up to 0.012×10-6,precision（RSD,n=12） 2.31%~4.78%.As tested by national primary standard substance of soil availability,the analytical result is satisfactory. |
