New inorganic nanofiltration membrane was obtained by covalent grafting of organo titanate agents on zirconia layer followed by hydrolysis. Grafting of zirconia by titanates with pyrophosphate groups (PP) was shown by the decrease of isoelectric point to about 5 of zirconia particles of same process history as the membranes. In order to further reduce the pore size of the grafted membrane, a pre-treatment...
The electrophoretic mobility of proteins was successfully determined by means of capillary electrophoresis (CE) with various background electrolytes (BGEs). The objective was focused on the variation in BGE physico-chemical composition and the consequential impact on the observed protein charge. Experimental and calculated mobilities, according to Henry's equation, versus ionic strength have been...
