The present work is focused on the homogeneous and heterogeneous photo-catalytic degradation of Hacid, a non-biodegradable dye intermediate from dye manufacturing industries, using Advanced Oxidation Processes (AOPs) such as UV, UV/H2O2, UV/H2O2/Fe 2+ (photo-Fenton process), UV/TiO2 and UV/H2O2/TiO2. Degradation experiments were carried out to optimize the amount of catalyst, effect of Hacid co...

Silver nanoparticles were prepared by microwave irradiation of silver nitrate solution with carboxymethyl chitosan as reducing agent and a stabilizer. The optical properties, morphology and structure were characterized using UV–Visible spectrophotometer, transmission electron microscope (TEM) and X-ray diffraction (XRD). Appearance of surface plasmon band at 413 nm indicated the formation of si...

Copper Telluride (CuTe) thin films have been successfully deposited on a glass substrate Fluorine Tin oxide (FTO) by electrodeposition technique. The absorbance was measured using M501 UV-visible spectrophotometer in the wavelength range of 200-900nm. Copper Telluride (CuTe) thin films were investigated at room temperature. Optical absorption study showed that CuTe films were of indirect band g...

Carbon nanotube-cadmium selenide (CNT-CdSe) composite was synthesized by a facile hydrothermal method derived from multi-walled carbon nanotubes as a stating material. The as-prepared products were characterized by X-ray diffraction, scanning electron microscopy with energy dispersive X-ray analysis, transmission electron microscopy (TEM), and UV-vis diffuse reflectance spectrophotometer. The a...

In this data article, we evaluated the daily fluoride contents in 20 household desalinators working by reverse osmosis (RO) process in Bushehr, Iran. The concentration levels of fluoride in inlet and outlet waters were determined by the standard SPADNS method using a spectrophotometer (M501 Single Beam Scanning UV/VIS, UK). The fluoride content in outlet waters were compared with EPA and WHO gu...

Nitrification inhibitors (Thiourea and nitrification inhibitor “A”) with urea fertilizer were used to enhance the nitrogen efficiency. Nitrification inhibitors and the amount of nitrogen were applied through urea fertilizer to rice seed in Column Lysimeters. The whole experiment was conducted with following treatments such as; urea application as a control at 2gN/10kg (200 kg N/ha), urea applic...
