WebWe first look at the effect of the colloid on the positive ions (often called counter-ions) in solution. Initially, attraction from the nega- tive colloid causes some of the posi- tive ions to form a firmly attached layer around the surface of the colloid; this layer of counter-ions is known as the Stern layer. Webmatter or hydrous oxides, counter ions (for negatively charged surface counter ions are cations, or positive ions) are attracted by the charged surface and accumulated close to …

WebAnion-exchange chromatography is a process that separates substances based on their charges using an ion-exchange resin containing positively charged groups, such as diethyl-aminoethyl groups (DEAE).
