摘要: Abstract Population growth and deteriorating health issues have led to an increase in the consumption of angiotensin receptor blockers (ARBs), such as losartan (LOR), for treating high blood pressure and, a result, frequent detection these drugs water wastewater. The present study focuses on oxidation LOR by UV photolysis, UV(/Fe2+)-activated persulfate (PS) hydrogen peroxide (H2O2) systems. effects operating parameters including pH value, reaction time, concentration oxidant activator efficacy treatment were studied. target compound degradation direct UV/PS UV/H2O2 systems proved be efficient followed pseudo-first-order kinetic model. application UV/oxidant even at lower PS or H2O2 concentrations resulted more than 95% 10 min. In addition, use UV/Fe2+-activated further kobs improving aqueous solution. effectiveness mineralization based total organic carbon (TOC) removal was also considered. optimized results studied obtained ultrapure used groundwater assess decomposition complex environmental matrix. Moreover, acute toxicity solutions before after luminous bacteria (Vibrio fischeri) investigated.
