The relative rates of degradation of three hydroxyl radical probe compounds (atrazine, fenuron and parachlorobenzoic acid (pCBA)) by Fe(III)/H(2)O(2) (pH = 2.85), Fe(III)NTA/H(2)O(2) (neutral pH), Fe(II)/O(2), Fe(II)NTA/O(2), Fe(II)/H(2)O(2) and Fe(II)NTA/H(2)O(2) (neutral pH) have been investigated using the competitive kinetic method.
The IHSS soil humic acid (HA) standard and two HAs from soils of very different origin (Chernozem and Ranker) were fractionated by tandem size-exclusion chromatography-polyacrylamide gel electrophoresis. From each HA, three fractions with different molecular sizes (MSs) and electrophoretic mobilities
Humic acids (HAs) from three soils of different origin (Chernozem, Ferralsol and Ranker) have been fractionated by coupling size exclusion chromatography (SEC) and polyacrylamide gel electrophoresis (PAGE) on three fractions (fractions A, B, C + D) with different molecular sizes
