11. Figure 1 shows a typical water sorption result from a DVS experiment for a microcrystalline cellulose sample. 12. This region is also called Henry's law region or linear region of the sorption isotherm. 13. This relationship between water activity and moisture content at a given temperature is called the moisture sorption isotherm. 14. Because the sorption to soil and sediment is considered high, dichlofenthion is not a highly mobile compound. 15. The overall conclusion of the study was that the organoclays studied have considerable capacity for heavy metal sorption . 16. In general, a vapor sorption isotherm shows the absorption " ( sorbate penetrates the bulk ). 17. The shape and location of the isotherm hysteresis can elucidate information about the sorption mechanism and sample porosity. 18. The sorption coefficient is a means of specifying a pesticide's tendency to bind to soil particles. 19. Research has also shown that pretreatment of glassware and plastic surfaces can reduce radionuclide sorption by saturating the sites. 20. A more general term is " sorption ", which covers absorption, adsorption, and ion exchange.
