photo -chemical degradation of 2, 4- dichlorophenoxyacetic acid (2, 4-d) in the effluent

2, 4-D Dichlorophenoxyacetic Acid Poisoning; Case Report and Literature Review

Background: 2, 4-dichlorophenoxyacetic acid, (2, 4-D) is a selective herbicide available as the acids, esters and several salts which vary in their chemical properties, environmental behaviour, and to a lesser extent toxicity. The salt and ester forms are derivatives of the parent acid. It is widely used as a weed killer. The 2, 4-D dimethylamine is one of the salts of this group. Case Presenta...

removal of 2, 4-dichlorophenoxyacetic acid (2, 4-d) from aqueous environments using single-walled carbon nanotubes

conclusions according to achieved results, it was defined that swcnts is a quite effective adsorbent in removal of 2, 4-d from aqueous environments. results maximum adsorption capacity of the swcnts was 979.6 mg/g at ph5, contact time 45 min, initial concentration of 5000 µg/l, and 23 ± 2 ◦c temperatures, when 97.96% of 2, 4-d herbicide were removed. the adsorption equilibriums were analyzed by...

Management of 2, 4- Dichlorophenoxyacetic Acid Intoxication by Hemodialysis: A Case Report

Background: The herbicide 2, 4-dichlorophenoxyacetic acid (2, 4-D) can cause moderate to lethal poisoning. Although urine alkalization has been recommended as the main treatment, hemodialysis (HD) may be more effective in severe cases. Case: On 24th June 2014, a 53- year-old man ingested a high amount of 40% 2, 4-D. He suffered from mouth and epigastric burning sensation, vomiting and nausea...

Study Degradation of 4-(2-Pyridylazo)Resorcinol Dye in Circulating Fludized Bed Photo Reactor Using ZnO Nanoparticles

Background & Aims of the Study: In this study, 4-(2-pyridylazo) resorcinol (PAR) as model azo dye was used. In spectroscopic measurements and studies of PAR reagent as a ligand are used to formation a complex with toxic metals. So, removal and degradation these compounds of wastewaters are necessary. The aim of this study is the degradation of PAR from aqueous solutions in circulating fludized ...
