摘要
本文在液氮温度下,测试了硫铁矿矿样在气体饱和蒸气压力范围内对N2的吸附过程及吸附量,用BET和BJH理论模型计算出硫铁矿矿样的孔体积和孔表面积。根据试验结果,探讨了硫铁矿的孔体积与孔比表面积的关系,及其对硫铁矿吸附能力的影响,即硫铁矿对N2的吸附能力与总孔体积、总孔比表面积呈正相关性。
At the temperature of liquid nitrogen the N2 adsorption process and adsorptive volume of iron pyrites samples are measured under the gas saturated vapour pressure. Using BET and BJH theoretical models the pore volume and specific surface area of iron pyrites are calculated. Based on results, it is discussed that the relationship among pore volume and total specific surface area, as well as the influence on iron pyrites adsorptive capacity.
