اشتراب

(تم التحويل من Sorption)
Gas–liquid absorption (a) and liquid–solid adsorption (b) mechanism. Blue spheres are solute molecules.

الاشتراب Sorption هي عملية طبيعية و كيميائية تصبح بها مادة ملتصقة بأخرى. Specific cases of sorption are treated in the following articles:

Absorption
"the incorporation of a substance in one state into another of a different state"[1] (e.g., liquids being absorbed by a solid or gases being absorbed by a liquid);
Adsorption
The physical adherence or bonding of ions and molecules onto the surface of another phase (e.g., reagents adsorbed to a solid catalyst surface);
Ion exchange
An exchange of ions between two electrolytes or between an electrolyte solution and a complex.

عكس الاشتراب هو الانتزاز desorption.

معدل الاشتراب

The adsorption and absorption rate of a diluted solute in gas or liquid solution to a surface or interface can be calculated using Fick's laws of diffusion.
