radicals was validated through radical quenching and electron paramagnetic resonances (EPR)

tests. BPA degradation pathways were proposed on the basis of LC-MS and GC-MS analyses.

Finally, a possible mechanism of catalytic PMS activation was proposed that involved electron

transfer from MnO or Mn2O3 to PMS with the generation of sulfate radicals, protons and

MnO2, as well as the simultaneous reduction of MnO2 by PMS. (C) 2016 Elsevier B.V. All

摘 要 :High iodine concentrations in groundwater have caused serious health problems

to the local residents in the Datong basin, northern China. To determine the impact of water-

sediment interaction and irrigation practices on iodine mobilization in aquifers, isotope

(H-2, O-18 and Sr-87/Sr-86) and hydrogeochemical studies were conducted. The

results show that groundwater iodine concentrations vary from 14.4 to 2180 mu g/

L, and high iodinegroundwater (>150 mu g/L) mainly occurs in the central area of the

Datong basin. Sediment iodine content is between <0.01 and 1.81 mg/kg, and the co-

occurrence of high iodine and high DOC/TOC concentrations of groundwater and sediment

samples in the deeper aquifer indicates

that the sediment enriched in iodine and

or ganic matter acts as the main

source of groundwater iodine. The Sr-87/Sr-

86 values and groundwater chemistry suggest

that aluminosilicate hydrolysis is the dominant

process controlling hydrochemical evolution
