[求助] 翻译4个句子,有关吸附内容(汉译英)

1, 浓度越低, Elvoich方程的线性拟合因子越高,这说明吸附剂在吸附低浓度污染物过程中,化学吸附占主导作用。
2, 该吸附剂吸附有机染料属于快吸附过程,这有利于提高吸附去除及后续光催化降解有机污染物过程的效率。
3,第二过程的速率常数比第一过程来的低,这说明颗粒内扩散是整个吸附过程的速率决定步骤。
4, Qe值随着 Ce值的增大而增加,该趋势在 Ce小于20mg.l-1之前属于快速增加过程,而在20 mg.l-1以后缓慢增加直至趋于平衡为止。

1. When concentration is lower, the linear approximate factor of Elvoich function is higher. This illustrates that absorption solution mainly uses chemical absorption as function during absorbing low-concentration contaminants.
2. It is a fast absorption process that this absorption solution process organic dye, which is good for increasing efficiency of absorption elimination and following light-enzyme degradation of organic contaminants.
3. The velocity constant of second process is lower than of first process, which shows that distribution in particle is velocity-determined step of entire absorption process.
4. The value of Qe increases when value of Ce increases. This trend is fast increase process before Ce is less than 20mgL-1 and increases slow to end in balance after 20mgL-1.
