摘要: The mass titration method, used for the point of zero charge determination, was extended to measurement surface density. results agree with common which is acid-base colloidal suspension. advantage that one does not need perform blank titration, instead simply adds metal oxide powder electrolyte aqueous solution known pH. To cover pH range above and below charge, two experimental runs are necessary.
