摘要
The behaviour of the title substances, which are components of the commercial plant growth stimulator Sviton, in differential pulse voltammetry at a hanging mercury drop electrode was studied and the optimum conditions were established for their quantitation over the concentration region of 1 .10(-7) to 1 . 10(-5) mol 1(-1). Additional decrease in the limit of determination was achieved in adsorptive stripping voltammetry, by which 4-nitrophenol and 2-nitrophenol can be determined within the concentration regions of 2. 10(-10) to 1. 10(-7) and 2. 10(-8) to 1. 10(-7) mol 1(-1), respectively, and 2,4-dinitrophenol and 2-methoxy-5-nitrophenol within the region of 2. 10(-9) to 1. 10(-7) mol 1(-1).
