Thermal degradation kinetics study of curcumin with nonlinear methods.
The results of TG/DTG when curcumin was used as the food colouring agent indicated that the processing temperature of the food should not exceed 190°C. The decomposition process of curcumin involvedExpand
Synthesis of nanoparticle zinc phosphate dihydrate by solid state reaction at room temperature and its thermochemical study
Abstract Nanoparticle zinc phosphate dihydrate was prepared by solid-state reaction at ambient temperature from Na3PO4·12H2O and ZnSO4·7H2O, and characterized by X-ray, Raman, FT-IR spectra and TEM.Expand
Concentration and separation of vanadium from alkaline media by strong alkaline anion-exchange resin 717
With strong alkaline anion-exchange resin 717 as the sorbent and NaOH solution as the eluent, a study on the sorption from alkaline solution and elution of vanadium(V), silicon(IV), andExpand
Preparation of LiZnPO4·H2O via a novel modified method and its non-isothermal kinetics and thermodynamics of thermal decomposition
The single phase α-LiZnPO4·H2O was directly synthesized via solid-state reaction at room temperature using LiH2PO4·H2O, ZnSO4·7H2O, and Na2CO3 as raw materials. XRD analysis showed that α-LiZnPO4·H2OExpand
Facile synthesis of hydrotalcite and its thermal decomposition kinetics mechanism study with masterplots method
Abstract The hydrotalcite, Mg4Al2(OH)12CO3·3H2O, was synthesized via low-heating solid-state reaction at 80 °C. The thermal decomposition of Mg4Al2(OH)12CO3·3H2O experienced two stages. The apparentExpand
