Chitosan isoelectric point
WebAlginate is also found to be a good candidate when particle charge inversion is achieved first with aluminum chloride. We also demonstrate that coagulant dosage is dependent on the initial pH of the suspension. When the initial pH of the dispersion is low, the isoelectric point is obtained for small dosage values. WebJul 3, 2007 · Albumin was adsorbed on these particles (after cross-linking with glutardialdehyde), and pH was controlled to obtain two conditions: (i) adsorption of positively charged albumin and (ii) adsorption of albumin at its isoelectric point.
