The aqueous solubility of twenty-seven insecticides and related compounds.
The aqueous solubilities of 27 insecticides and related compounds were determined. Diazinon, fensulfothion and paraoxon had solubilities greater than reported in the literature. The presence of impurities and/or additional components in the mixture altered the measured solubility values. Addition of acetone in amounts up to 1% (volume) produced increases in parathion solubility up to 11%. The p...
متن کاملStability of parathion and DDT in dilute iron solutions.
Dilute FeCl3 and Fe(NO3)3 solutions degraded parathion to paraoxon and p-nitrophenol. Initial hydrolysis products of iron appeared to have the greatest catalytic activity which decreased as these hydrolysis products aged. The Fe3+ ion was less catalytically active than its hydrolysis products for parathion degradation. pH was not a factor in parathion degradation in this study. AlCl3 solutions ...
متن کاملFurther water solubility determinations of insecticidal compounds.
The aqueous solubility of 39 insecticidal and related compounds was determined at 20 +/- 1.5 degrees C, using a previously described shaking and centrifugation method. Fenamiphos, fenthion and methidathion produced values substantially less than those reported in the literature whereas, aminocarb, diazinon, dicapthon, pirimiphos-ethyl and pirimiphos-methyl gave solubilities substantially greate...
متن کاملAdvanced oxidation processes in the treatment of trifluraline effluent.
The treatment of an effluent from the production of trifluraline was studied using a 1-L, semi-batch, tank-stirred glass reactor for performing three different advanced oxidation processes (photoperoxidation, Fenton, photo-Fenton). A commercial, medium-pressure mercury lamp was used for sample irradiation. The degradation was monitored by measurements of absorptiometric color reduction, UV-visi...
