Quantitative Adsorption of Ammonium Salt of Polyacrylic Acid on Nano size Y TZP
Source abstract
Abstract
The quantitative adsorption of ammonium salt of polyacrylic acid on nano size Y TZP powder was investigated by using UV adsorption spectrum The adsorption of PAA NH 4 decreases as pH increases, because the PAA NH 4 is more negatively dissociated When the pH is 1 02, the adsorption type belongs to high affinity The highest adsorption percent can reach as high as 98% If initial pH falls in the range of 2 7 to 13 6, the pH of the supernate is near to 8 3 and their Zeta potential is in the range of 35 to 40mV In a wide pH range the adsorption ability is less effected by the initial pH, due to the high buffer ability of PAA NH 4
