Preparation and characterization of acetate cellulose electrospun nanofibers membrane: Potential application on wastewater treatment.

Development of nanofiber membranes with the ability to remove organic dye such as Indigo Carmine (IC) from effluent wastewater is of immense help to the textile industry. In the present study, we investigate the preparation of cellulose acetate (CA) nanofiber membranes with optimized performances using electrospinning technique for effective removal of Indigo Carmine (IC) dye. Electrospinning parameters and solvent system containing acetic acid were adjusted to obtain CA nanofibers membranes which better suits dye removal application.

Effect of coating method on the structure and properties of a novel PbO anode for electrochemical oxidation of Amaranth dye.

This study deals with the electrochemical degradation of Amaranth in aqueous solution by means of stainless steel (SS) electrodes coated with a SiO interlayer deposited by Plasma Enhanced Chemical Vapour Deposition and a modified PbO top layer deposited by continuous galvanostatic electrodeposition. The morphological characterization of the PbO top-layer performed by Field Emission Scanning Electron Microscope put in evidence that the SiO, interlayer allows obtaining a more integrated PbO/SS electrode with a very homogeneous PbO film. The composition of the lead oxide layer was investigated by X-ray Diffractometry, showing that the β-PbO/α-PbO ratio in the top layer deposited on the SiO film was four times higher respect to the one deposited directly on the stainless steel surface.
