Removal of 2,4-diclorofenoxyacetic Acid (2, 4–D) with Carbonized Peanut Shell
Abstract: Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Removal of 2,4-diclorofenoxyacetic acid (2, 4–D) has been studied using carbonized peanut shell (CPS). The effects of experimental parameters such as the initial pesticide concentration, contact time and temperature were evaluated. The concentrations of solutions of 2,4-D used were 0.4 and 0.6 mg/L and the temperatures were 25, 35, 45 and 55 °C. Some adsorption isotherms such as the Langmuir and …

Mono(acetylacetonato)zirconium(IV) Aryloxides: Synthesis, Reactivity and Thermoanalytical Investigation
Abstract: Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 A series of novel zirconium(IV) complexes, formulated as ZrCl3−n(acac)(OArI–V)n (where n =− 3; –OArI = OC6H4Cl-2, –OArII = OC6H4Cl-4, –OArIII = –OC6H3Cl2-2,4, OArIV = –OC6H3Cl2-2,6 and OArV = –OC6H2Cl3-2,4,6) were synthesized by reacting ZrCl3(acac) with corresponding substituted chlorophenols in separate experiments. The complexes were characterized by elemental analysis, molar conductance measurements, molecular weight determination, spectroscopic techniques (1HNMR and IR) and thermal …
