Corrosion Properties of 70SiO2-15TiO2-15ZrO2 Ceramic Membrane

The 70SiO2-15TiO2-15ZrO2 membrane was prepared by a sol-gel procedure. The corrosion behavior of microporous toplayers along with the membrane characterization in terms of pore size, surface area, pore volume and weight loss is described. The final ceramic membrane with a thickness of 400 nm and uniform surface was obtained. This membrane confirmed the fine microporous characteristic with mean ...

FABRICATION AND CHARACTERIZATION OFHIGH PERFORMANCE CERAMIC MEMBRANE HAVINGNANOMETRE PORES

Abstract: In this study, carbon nanotubes (CNTs) were grown directly in the pores of micro porous pyrex membranesand consequently ceramic membranes with very fine pores and high porosity were achieved. Our experiment was donein two stages. Initially cobalt powder with different percent was homogeneously mixed with pyrex powder. In order toproduce row membranes, each of these mixtures were compa...

Decolorization of Dyeing Effl uent by Novel Ultrafi ltration Ceramic Membrane from Low Cost Natural Material

This paper is devoted to the application of new low cost ceramic ultrafi ltration membranes material coming from the Tunisian ores (mud) which is usually considered as disastrous for the environment. A ceramic tubular support previously elaborated from mud was coated in the lumen side by slip casting method. After sintering at 650°C, the coated membrane shows homogeneou...

In situ ion substitution of sodium gluconate: Comparison of bipolar membrane electrodialysis and electro-membrane reactor for producing gluconic acid

Based on the home-made cation-exchange membrane (CEM) and bipolar membrane (BPM), electrodialysis with bipolar membrane (EDBPM) and electro-membrane reactor with three compartments (EMR-3) were developed to achieve in situ ion substitution and recovery of gluconic acid (GLH) from its sodium salt. Physicochemical and electrochemical properties of CEM and BPM were studied to assess their...
