Effects of water quality on the coagulation performances of humic acids irradiated with UV light

Wendong WANG,Qinghai FAN,Zixia QIAO,Qin YANG,Yabo WANG,Xiaochang WANG

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 1,   Pages 147-154 doi: 10.1007/s11783-014-0749-7

Abstract: Our results suggested that UV light radiation could effectively improve the removal rate of humic acidlight.After UV light radiation, the removal rate of the nitro-humic acid (NHA) increased from 20% to 60% inlight radiation.The formation of positive charged sites after UV light radiation was considered to be the primary factor
