为研究吸附剂吸附的原理和影响因素,采用数学建模和模拟方法对Langmuir方程的常量Γ∞进行了定量分析,发现吸附剂总表面积是影响吸附能力的主要因素,吸附剂吸附能力随总表面积增大而增大,随粒径减小而急剧增大,悬浮物颗粒的几何形态影响甚小。天然状态下,单位水体悬浮物含量的不同将导致总表面积的不同,进而影响被吸附重金属的量。总之,改变悬浮物颗粒表面都会影响试验精度。
In order to study the principle and influencing factors of adsorbent adsorption, mathematical modeling and simulation methods were used to quantitatively analyze the constant Γ∞ of Langmuir equation. It was found that the total surface area of adsorbent was the main factor affecting the adsorption capacity. The adsorption capacity of adsorbent varied with the total surface area Increases with increasing, with the particle size decreases sharply increased, the geometry of suspended particles little effect. Natural state, the unit of suspended solids content of water will result in different total surface area, thereby affecting the amount of adsorbed heavy metals. In short, changing the surface of suspended particles will affect the test accuracy.
