The capability of Scenedesmus obliquus to remove cations(K+,Na+,Ca2+,Mg2+) from saline- alkaline water was investigated at different salinities(0,5,10,15,20,25) and carbonate alkalinities(0,5,10,15,20,25,30,35 mmol/L)...The capability of Scenedesmus obliquus to remove cations(K+,Na+,Ca2+,Mg2+) from saline- alkaline water was investigated at different salinities(0,5,10,15,20,25) and carbonate alkalinities(0,5,10,15,20,25,30,35 mmol/L).K+,Na+,Ca2+,and Mg2+in saline-alkaline water were efficiently removed by S.obliquus.The maximum removal of the cations(29.37 mg for K+,185.85 mg for Na+,23.07 mg for Ca2+,66.14 mg for Mg2+) occurred at salinity 25.The maximum removal of K+(2.28 mg),Na+(6.62 mg),Ca2+(1.01 mg),and Mg2+(0.62 mg) occurred at carbonate alkalinities of 25 mmol/L for K+,35 mmol/L for Na+,20 mmol/L for Ca2+,and 25 mmol/L for Mg2+,respectively.Under a salinity stress,the concentration of Na+in S.obliquus increased significantly,while that of K+decreased significantly.The concentrations of Ca2+and Mg2+decreased as well.The ratios of K+/Na+,Ca2+/Na+,and Mg2+/Na+were significantly lower in all salinity treatments than those of the control.Under alkaline stress,the concentrations of Na+and K+ in S.obliquus decreased significantly and the ratios of K+/Na+,Ca2+/Na+,and Mg2+/Na+were significantly higher in all treatments than in the control.Moreover,the concentrations of Ca2+and Mg2+in S.obliquus at alkalinities of 5–10 mmol/L were significantly higher than those of the other treatments.The removal of Na+by S.obliquus mainly occurs through biosorption,and Mg2+ and Ca2+ were removed through both biosorption and bioaccumulation.展开更多
