A Study of Oxalic Acid Adsorption on the Surface of Natural Mica

This paper reports an increment of conformal metal oxides or nonmetal oxides films with good crystallinity coating on natural mica synthesized by liquid phase deposition. PEG1000 and KH550 were used to increase the adsorption of oxalic acid on the mica surface. Hence, the metal ions can react with the oxalic acid, resulting in uniform and compact thick films. The potasrmanganate titration and infrared ssium pepectroscopy were adopted to obtain the optimum dosage of PEG1000 and KH550. It is shown that the condition with the usage of PEG1000 of 0.4 g/L, KH550 of 9.76 g/L, temperature of 30 °C and mixing of 4 hours is appropriate.
