本文介绍了一种用紫外分光光度计测定稀禾定残留量的方法,回收率为76~83%,最小检出限为0.04ppm。在常用量情况下,稀禾定在棉籽中无残留,在土壤中消解极快。
In this paper, a method for the determination of spironolactone residues by UV spectrophotometry is described. The recovery rate is 76-83% and the minimum detection limit is 0.04ppm. In the case of the amount of commonly used, thin seeding in cottonseed no residue in the soil digestion very fast.
