Which article are you evaluating?
Dialysis (chemistry)

The above link have the data about Dialysis. This is a technique used to removal of small molecules from larger molecules through semi permeable membrane. This works on the principle diffusion

Why you have chosen this article to evaluate?
Although I have a abundance of articles. But, this article attracts me a lot to go through. Actually Dialysis is a process where we used to separate smaller molecules lite salts, reducing agents from larger molecules like protein , DNA, Polysaccharides.Semipermeable membrane have pores in it which allows only small molecules until solution reaches equilibrium. DIFFUSION ,DIALYSIS, OSMOSIS, ULTRA FILTRATION are the principles of dialysis. Diffusion is the basic principle of dialysis where moment of molecules moves from higher concentration to lover concentration. Dialysis has been classified into two they are DIFFUSION DIALYSIS,ELECTRODIALYSIS Where Electrodialysis is further divided into 3 types DONNAN DIALYSIS, REVERSE ELECTRODIALYSIS, ELECTRODIALYSIS.

The factors effecting the process is sample volume, size of the volume being separated, the membrane used and the geometry of the membrane which affects the diffusion distance.

Firstly dialysis is used to separate sucrose from gum Arabic solutes. Crystalloids are diffusable solutes who’s pass through the semipermeable membrane and membrane colloids are do not pass through membrane. The semipermeable membrane is made up of cellulose or with synthetic polymers. This is a technique where it is used for medical purpose to purify the blood.

Diffusion dialysis is the spontaneous separation process where the driving force produces the separation concentration gradient. Electrodialysis is the process of separation uses ion-exchange membrane and electrical potential as driving force

Entropy increases and the Gibbs energy will get decrease’s, Anion exchange membrane and cation exchange membrane depending on the compounds to search.The most common performed dialysis are SLIDE-A LAYER,FLOAT -A LAYER, PUR-A LAYER  /D-TUBE/GEBA SLEX

Diffusion consumes lowest energy but it is low processing capability, it can operate easily and low cost.
