Abstract
The aim of study was to determine effect of 1-alkyl-3-methylimidazolium ionic liquids with tetradluoroborate anion on activity of soil peroxidases. The experiment was carried out in laboratory conditions with samples of loamy sand (Corg 8.71 g · kg–1, pHKCl 6.36), sandy loam (Corg 10.92 g · kg–1, pHKCl 6.81) and sandy clay loam (Corg 33.81 g · kg–1, pHKCl 7.13). Samples were sieved through a 2-mm mesh, and then three ionic liquids: 1-butyl-3-methylimidazolium tetrafluoroborate [BMIM][BF4], 1-bhexyl-3-methylimidazolium tetrafluoroborate [HMIM][BF4], and 1-octyl-3-methylimidazolium tetrafluoroborate [OMIM][BF4] at the dosages of 0, 10, 100, and 1000 mg · kg–1 were added to soil. Activity of peroxidases was measured spectrophotometrically on days 1, 3, 7, 14, 28, 56 and 112. Application of different dosages of all ILs caused mainly significant changes in activity of peroxidases. Changes in activity of peroxidases depended on the dosage of ionic liquids, incubation time, and soil properties. The effect of ILs on activity of peroxidases increased not only with an increasing dosage, but also with elongation of alkyl substituents in the cation. The highest impact of ILs on activity of peroxidases was observed in loamy sand.
