| 1. | The adsorption characteristics of cadmium in three textured soils were described by freundlich isotherms , whereas cadmium transport was described as a convection - dispersion process 其中,镉的吸附用2种不同的freundlich吸附等温线来拟合,运移过程作为对流-弥散过程来描述。 |
| 2. | The isotherm of darkened sand adsorbing these three kinds of heavy metal accorded with freundlich isotherm . thermodynamics study indicated that the adsorption course is spontaneous , endothermic and unreversible 热力学研究表明黑化砂吸附三种金属的过程是自发的、吸热的、不可逆的。 |
| 3. | The traditional freundlich isotherms were compared with the two - species freundlich isotherms , the effects of the organic matter content ( om ) and ph were considered , and adsorption parameters affecting movement of cadmium in soil were gained 比较了freundlich吸附等温线和考虑了ph值、有机质含量对吸附影响的两组份freundlich ( twospeciesfreundlich , 2sf )吸附等温线的优缺点,分析了有机碳、 ph对镉在土壤中吸附特性的影响。 |
| 4. | The redox potentials of chloroform are more than 500mv and electrosorption is only controlled by electric field and adsorption of granular activated carbon . the tests of adsorptions also testify it . the freundlich isotherm equation q = kc n is used for fitting the data 另外,氯仿的电解氧化还原电位大于500mv ,因此,此电场范围不会分解氯仿,回收率实验与色谱分析也证明了电场只对活性炭的吸附起催化作用,而不改变吸附剂与吸附质的内部性质。 |
| 5. | Adsorption isotherm of activated alumina and bone char can be described by langmuir adsorption isotherm in the form qe = 0 . 72cy ( l + 0 . 074ce ) and freundlich isotherm in the form qe = 0 . 88ce1 / 1 . ' 94 respectively . continuous - flow column experiments show there have higher removal capacity for activated alumina and bone char when empty - bed contact time was controlled within 12 ~ 15min and about 15min separately 对可利用吸附容量和实际利用吸附容量的理论分析说明,连续处理活性氧化铝停留时间控制在12 15min较好,此时吸附容量利用率较高,约为80 ,骨炭停留时间控制在15min较好,吸附容量利用率约为75 。 |
