利用化学全分析、XRD分析、原子力显微镜等方法对内蒙古产黑色电气石进行测试表征,并研究了该电气石对海水pH值的影响,探讨了电气石用量、海水盐度、初始pH值等因素对pH调控的影响.结果表明,电气石能够调节初始pH值为3和10的海水pH值分别至7.9和8.1;电气石对低盐度海水pH调控速率大于高盐度海水,处理120min后初始pH均为5,盐度为5、10、15、20、35的海水pH分别增加了3.24、3.16、3.06、2.99、2.85;电气石对海水电导率基本无影响.本研究为将电气石应用于调控水产养殖水体pH提供了实验基础.
The effects of the tourmaline on the pH of seawater were studied by means of chemical full analysis, XRD analysis and atomic force microscopy. The effects of tourmaline dosage, seawater salinity, initial pH and other factors On the regulation of pH.The results show that tourmaline can adjust the initial pH value of seawater pH 3 and 10 to 7.9 and 8.1 respectively; tourmaline for low salinity seawater pH control rate is higher than the high salinity seawater, 120min after the initial treatment pH was 5, salinity was 5,10,15,20,35 seawater pH increased by 3.24,3.16,3.06,2.99,2.85 respectively; tourmaline little effect on sea water conductivity.This study is to tourmaline application It provides the experimental basis for regulating the pH of aquaculture water.
