Liquid-liquid extractive-spectrophotometric studies of sodium ion complexes of 18crown-6(18C6), dibenzo-18-crown-6(DB18C6), 15-crown-5(15C5), and 12-crown-4(12C4) and anionic dyes [4-(2-pyridylazo)-resorcinol monosodium salt monohydrate (PAR), Eriochrom Black T (EBT), and methyl orange (MOR)] and sodium picrate (PICRAT) as the counter ion are described. The overall extraction equilibrium consta...
Background and Objective: PACT is an adsorption- degradation process through which slowly or non-biodegradable waste water compounds such as dye can be degraded. This study was carried out to evaluate the efficacy of PACT in removal of dyes form textile industry wastewaters. Materials and Methods: This research was carried out in pilot scale. The pilot design had two parts: an aeration tank wit...
Background and Objective: Acid dyes are synthetic organic compounds with complicated chemical structures which their treatment are difficult and costly. Discharchig of these dyes into the environmen causes harmful effects on ecosystem and water quality. In this study efficiency investigation of photo-fenton process in removal of acid green 20 dye from wastewater of textile industries was assess...
Background and purpose: Industries are one of the main sources of producing wastewater accounting for 20% of water pollution. Treatment of dye wastewaters is one of the major challenges in textile industry. The aim of this study was to investigate the performance of advanced oxidation processes, Fenton-Peracetic acid and Photo-Fenton-Peracetic acid for removal of methylene blue (MB) dye from ...
octanoate or decanoate per mol of albumin caused a decrease in dye binding (dye/protein molar ratio 1 : 1), which, in contrast with additional fatty acid, was very pronounced: 1-8mol of palmitate or stearate resulted in a small, and apparently linear, displacement of Phenol Red. The displacement effect of 1-5 mol of oleate, linoleate or linolenate per mol of albumin was comparable with that of ...
Background: With the increasing concern for health and nutrition, dietary fat has attracted considerable attention. The composition of fatty acids in the diet is important because they are associated with major diseases including cancers, diabetes, and cardiovascular disease. The fatty acid synthase (FASN) and stearoyl-CoA desaturase (delta-9-desaturase) (SCD) genes affect fatty acid compositio...
The photoinduced electron transfer between either cationic 5,50-dichloro-3,30,9-triethylthiacarbocyanine (1) or a structurally similar anionic dye (2) and appropriate donors, e.g. ascorbic acid, and acceptors, e.g. methyl viologen, was studied by ns-laser photolysis. In aqueous solution the dyes in the ground state are present as an equilibrated mixture of dimers and monomers, whereas the tripl...
In the present study, various size of Zinc Oxide Nanoparticles (ZnO NPs) was synthesized via Sol-gel method. The photocatalytic activity of the synthesized ZnO NPs was investigated for the Decolourization of three different colored dyes viz. Congo Red, Acid Blue 9 and Coomassie Brilliant Blue R-250 under UV lamp. Zinc Chloride (Zncl2) and Sodium Hydroxide (NaOH) were ...
in this study, a new adsorbent, silver nanoparticle loaded on activated carbon (ag˗np˗ac) was used for removal of acid yellow199 (ay 199) dye. this novel material was characterized and identified by different techniques such as brunauer, emmett and teller (bet), field emission scanning electron microscopy (fesem), x-ray diffraction (xrd) analysis. unique properties of this adsorbent such as hig...
