In this research, the specific electrodes were prepared by metal-organic chemical vapor deposition (MOCVD) in a hot-wall CVD reactor with the presence of O 2 under reduced pressure. The Ir protective layer was deposited by using (Methylcyclopentadienyl) (1,5-cyclooctadiene) iridium (I), (MeCp)Ir(COD), as precursor. Tetraethyltin (TET) was used as precursor for the deposition of SnO 2 active layer. The optimum condition for Ir film deposition was at 300°C, 125 of O 2 /(MeCp)Ir(COD) molar ratio and 12 Torr of total pressure. While that of SnO 2 active layer was at 380°C, 1200 of O 2 /TET molar ratio and 15 Torr of total pressure. The prepared SnO 2 /Ir/Ti electrodes were tested for anodic oxidation of organic pollutant in a simple three-electrode electrochemical reactor using oxalic acid as model solution. The electrochemical experiments indicate that more than 80% of organic pollutant was removed after 2.1 Ah/L of charge has been applied. The kinetic investigation gives a two-step process for organic pollutant degradation, the kinetic was zero-order and first-order with respect to TOC of model solution for high and low TOC concentrations, respectively.

To improve the hydrophilic property of natural rubber latex (NR), various methods for combining hydrophilic polymers; ie, mechanical blending (MB), semi-latex interpenetrating polymer network (semi-LIPN), and latex interpenetrating polymer network (LIPN), were studied. Polyacrylamide (PAM) and phthalated chitosan (PhChi) were chosen as hydrophilic polymers for this study. The desired membranes must possess sufficient tensile strength and high water sorption selectivity. The potential membrane usable for pervaporation dehydration of aqueous azeotrope ethanol was the LIPN type prepared from prevulcanized latex and PAM with 60/40 ratio and with 1% EGDM.
