Abstract:
Objective To develop a method to determine molybdenum in radix puerariae and the soil. Methods A method for determination of trace molybdenum in radix puerariae and the soil where it growth by single sweep polarography has been used. Results The linear range was 0.010-1.0 ?g/ml, r=0.999 0, the detection limit was 6.0?10-3 ?g/ml, the recovery rates were 98.0%～106.0%, RSD was 2.2%-4.8%. Conclusion This method is suitable for the determination of molybdenum in radix puerariae and the soil. The content of Mo in radix puerariae is related to that in the soil.
