【摘要】 通过简单方法将电气石粉体和磷酸盐粉体包覆成小球,研究了两种复合小球对水体的溶解氧(Dissolved Oxygen,DO)含量和pH值的影响,发现两种复合小球均能使水体DO值增大,且具有缓释、立体增氧和长时间维持增氧效果的功能;电气石颗粒的电极性影响水体的氧化还原电位,调节溶液pH值趋向弱碱性;经磷酸盐复合小球处理后的水体pH值减小,并从理论上对上述试验结果进行了探讨。更多还原

【Abstract】 In this paper,tourmaline powder and phosphate powder globules were prepared with easy method,and the influences of the composite globules on the dissolved oxygen content and the pH value of the water were tested.Results showed that oxygen concentrations of water was increased up to 2.01 mg·L-1 and 1.97 mg·L-1,respectively,and the increasing effect was slow-released and lasting.The electrode character of tourmaline particle influenced the redox potential of water and regulated the pH value of solution to be alkalescent.The phosphate globules made the pH value of the water decrease.The activated mechanism of mineral powders on water was also discussed.更多还原
