activity of this new Fenton-like catalyst can be obtained at different initial pH in range of 3.0-

9.0. The time evolution of degradation ofBPA followed pseudo-first-order kinetics,
and the first-order rate constants showed a linear relationship with parameters of initial

pH, catalyst dosage and concentration of BPA. However, the H2O2 dosage showed a dual
effect on BPA degradation because excessive H2O2 addition lead to scavenging of hydroxyl

radicals ((OH)-O-center dot). The investigation of working mechanisms of MS Fe
suggested a synergistic effect ofhomogeneous and heterogeneous degradation reaction,

wherein a strong acidic environment, abundant surface-bonded hydroxyl group and electron-
mediating effect of sulfur all contributed to fast activation of H2O2. Overall, this new material

overcomes the limitation of narrow working pH range and shows a fast oxidation of BPA
with a low H2O2 and catalyst dosage, would have a good potential for environmental

application. (C) 2015 Elsevier B.V. All rights reserved.

摘 要:Mulched drip irrigation for cotton field is an effective measure for the
utilization of saline water, and the regulation of soil water and salt. However, the reasonable

m e t hods for qua nt i fyi ng
actual evapotranspiration (ET) an

d deep percolation of recharge
to groundwater are still not very

well understood, which restricts
the accurate regulation of soil

wa t e r a nd sa l t for c ot t on
growth in oasis. In this paper, a set of experiments of mulched drip irrigationwith brackish

water were conducted in a typical arid region of Tarim basin in southern Xinjiang, China.
The irrigation events were recorded, and ET and fluctuations of groundwater table were

carefully measured for two consecutive irrigation periods of flowering and boiling stages.
