After considering all the different parameters a simple, rapid, sensitive and selective method for spectrophotometric determination of trace levels of iron(III) was proposed based on the formation of (Fe -MHP) complex at pH 2.5 (λmax = 640 nm, ɛ = l×104 L mol−1 cm−). The ...
Ammonium hydroxide was added carefully to the resulting mixture until the pH was approximately 1- 2. The resulting precipitate was filtered and dried to afford the title compound (69.5 g, 83percent). δ4-Methylpyridin-3-ol (52; 8.4 g, 78.5 mmol) was added to ice cold cone. H2S0 more ...

Chlorpyrifos was synthesized by reacting of 3,5,6-trichloro-2-pyridinol sodium(1 mol) with O,O-diethyl phosphorochloridothioate(1 mol) via aqueous phase(pH=11-13) reaction and benzyltrimethyl ammonium chloride as catalyst at 60 °C for 3 hrs,and the yield and purity of chlorpyrifos were ...
of the compound with heat and the pH of the reaction mixture is adjusted to 2-6 by adding an acid such as sulfuric acid or hydrochloric acid to give the title substance such as 3,5,6-trichloro-2-pyridinol. During the hydrolysis, the reaction mixture is taken out of the reaction tank ...
After completion of the reaction, the autoclave is cooled down lower 100 deg.C, the reaction mixture is diluted with water and neutralized to pH8. The precipitated crystals are filtered and dried to give the subject compound.SHISHIDO SETSUO...
CP degradation was associated to microbial growth of the strains, pH modification, glucose consumption and organic acids excretion in the liquid medium. This work constitutes one of the few reports of Streptomyces as CP-degraders. Given the high CP degradation observed here, the Streptomycetes ...
The TCP degradation rate and quantum yield increased with solution pH up to a constant maximum value of (6.40 ± 0.046) × 10 3 cm 2 mJ 1 and 0.178 ± 0.002 mol E 1 respectively, at pH 5 and above. Addition of 5 mg L 1 H 2 O 2 to generate OH radicals led to an increase in...
However, optimal degradation of CP was achieved at 37°C and neutral pH (7.0) at an initial inoculum density 2×107 colony forming unit/mL of culture medium. Kinetic parameters for CP degradation by M esorhizobium sp. HN3 were estimated at different initial concentrations. Cultures exhibited ...
