It states that the chairman and members of the PZC
, other than ex-officio members, shall hold office for a term of three years, and shall be eligible for appointment for another term but no chairman and members shall be eligible for re-appointment after two consecutive terms.
So, the pH value at which surface positive charge equals to the surface negative charge is called the point of zero charge, PZC
or [pH.sub.0] .
The negative delta pH (-1.03) and PZC
lower than the p[H.sub.H2O] (4.18) indicate a predominance of negative charges, which can promote cation adsorption.
Salt addition method was applied to determine the PZC
PCQ, PCK and PZC
are funds that invest primarily in California municipal bonds and seek to provide current income exempt from federal and California income taxes.
With these results, it is possible to note that there was an indication of the electrostatic adsorption due to the negative delta pH (-1.03) and PZC
lower than the [pH.sub.H2O] (4.18).
was then estimated from the plot of IpH (pHf - pHi) versus pHi.
In the PZC
model, the elastoplastic stiffness tensor [D.sup.ep] is defined as follows:
According to zeta potential measurement, minerals diaspore, kaolinite, illite and pyrophyllite, operating PZC
diaspore, kaolinite, illite and pyrophyllite, were respectively about 6.68, 3.65, 2.88 and 2.51 It was suggested to conduct the separation by using diaspore floatation method of kaolinite, illite and pyrophyllite, with a cationic collectors with a pH between 2 and 7.
