Product Information

synthesized Sr 1-xBa xSnO 3 powders and observed that the photodegradation of remazol golden yellow is strongly influenced by the composition of the photocatalyst. UV radiation favored the discoloration of the solution, but the results were relatively different when the photocatalytic tests were conducted under different conditions. This registry includes all substances described since 1957, plus some substances from as far back as the early 1800s; [3] it is a chemical database that includes organic and inorganic compounds, minerals, isotopes, alloys, mixtures, and nonstructurable materials (UVCBs, substances of unknown or variable composition, complex reaction products, or biological origin). Synthesis of the CaSnO 3: CaSnO 3 powder was synthesized by a modified Pechini method, as described in previous work on SrSnO 3 21 21 G.

When pH>pH PZC, the material surface becomes negatively charged, which favors the adsorption of cations 41 41 H. Tritan is a modern plastic with glass-like properties, completely BPA-free and does not change the taste of drinks. The percentage of discoloration and degradation of the dye solutions were quantified using a UV-vis spectrophotometer (UV-2550, Shimadzu) in absorbance mode by measuring the absorbance of the solution at 410 and 240 nm, respectively 25 25 M. UV-vis spectra of RNL azo-dye, after adsorption and after photocatalytic test at pH 6 (a) and pH 3 (b), in the presence of CaSnO 3. Insulated bottles keep drinks at the desired temperature for prolonged periods, while filtered bottles provide the added benefit of purifying water on-the-go.According to the evaluation of the PZC, a positive surface charge density is obtained at pH 3, while a slightly positive charge density is attained at pH 6.

F. Teixeira, “Avaliação da eficiência do uso de hidrotalcitas calcinadas na remoção de azo corantes aniônicos presentes em efluentes de indústria têxtil”, Diss. Neste trabalho, perovskita de CaSnO 3 foi sintetizada pelo método Pechini modificado, em 800 ºC, e caracterizada por difração de raios X, espectroscopia de UV-vis, espectroscopia de infravermelho e espectroscopia Raman. O ponto de carga zero (PZC) e os resultados fotocatalíticos indicaram que em pH 3 existiu uma predominância de um mecanismo direto, enquanto em pH 6 prevaleceu o mecanismo indireto.At pH 3, a higher electrostatic attraction between the positive surface and negatively charged dye molecule favored the direct mechanism of photocatalysis, as indicated by the adsorption results.
