摘要：

The adsorption of various phosphonic acids in sand and loam was studied. Samples of both soil types were sieved into three different fractions according to particle size. The fractions used were in the range 0-100, 100-200 and 200-400 m. The performance of the capillary electrophoresis equipped with contactless conductivity detection was investigated. The limit of detection for the phosphonic acids tested was in the range 0.11-1.4 ppm. Different isotherms were constructed for all adsorption curves. Adsorption was found to be higher in sand than in loam when the Langmuir adsorption isotherm was used. The adsorption of methylphosphonic acid was higher than that of other phosphonic acids due to the smaller molecular size of the former.
