Colloid Charge Capacity — Its Measurement, Problems and Promise

Conference paper

Abstract

The interfacial charge capacity of colloids (or CCC — colloid charge capacity) in water is potentially a “master” variable for dealing with numerous colloidal phenomena, especially dosage control in charge-neutralization coagulation. Colloid charge titration (CCT) analysis can quantify this important extensive charge property — distinct from zeta potential (ζ), the intensive expression of interfacial charge. The analysis involves titration of a colloid suspension with an oppositely charged, strongly binding polyion of known charge equivalence, past the charge-neutralization reaction equivalence point (i.e., zero point of charge or ζ = 0 mV) employing an appropriate endpoint detection method. The objectives of this article are to [1] explore the original dye based endpoint method by instrumental means and identify its capabilities and limitation, [2] review relevant literature to reconcile these findings with the “underwhelming” use of this otherwise promising technique, and [3] explore its potential in coagulation chemistry control.
