“…In this research, first of all, it was necessary to select an ionic salt with a suitable concentration. Salt promotes phase separation by increasing the movement of the chemical constituent between different phases and declining the Cloud Point Temperature (CPT) 49 . When the temperature enhances over the cloud point of the surfactant, it causes the micelles to lose water and produce a cloudy solution, resulting in phase separation.…”

Cloud point extraction (CPE) was used in this work to eliminate anionic dyes, Cresol red and Methyl orange, in the form of binary combinations. To remove these dyes from aqueous solutions, Triton X-100 was utilized. We chose wavelengths of 365 nm and 520 nm for Cresol red and Methyl orange, respectively, using a derivative spectrophotometer and first-order derivatives. The response surface methodology was then utilized to ascertaint he effect of surfactant concentration, temperature, and time on the dyes' elimination processes. The quadratic mathematical model obtained from the Box-Behnken design (BBD) matrix was used and developed to estimate the influence of each variable and its relationship with the elimination parameters. Using model equations and comparison between predicted and empirical values, coefficients of determination (R2) bigger than 0.97 were obtained. By applying variance analysis, significance and anticipation of models were validated, and process variables were estimated. The data demonstrate that the mentioned dyes adsorption may be described using the model of pseudo-first-order in kinetic modelling. The data illustrates that the analyzed dyes adhere to the Langmuir model, with a correlation value of 0.86 for Cresol red and 0.87 for Methyl orange. The monolayer capacity (Qmax) was determined to be 0.77 mol/mol for Cresol red and 26.41 mol/mol for Methyl orange.

“…Response surface methodology (RSM) [37,38] has been applied for the characterization of acidic mixtures [39,40] and basic mixtures [41] on HPLC. This technique can be used in research concerning natural products [42] in place of traditional experimental designs that make use of a one-variable-at-a-time design.…”

The effects of the flow rate, the injection volume, and the mobile phase ratio on the retention time and the resolution of separation of silybin were examined using Box-Behnken design on a symmetry prep C18 column. The optimum values of the operating parameters were 8 ml/min for the flow rate, 3 ml for the injection volume, and 40:60 for the mobile phase ratio. Under the optimal conditions, the retention time of silybin B was 59.552 min and the resolution of silybin A and silybin B was 1.0696, where the purities of the obtained silybin A and silybin B were both over 99% by ultra-performance liquid chromatography. The preparative-liquid chromatography simulation was applied with COMSOL. The optimization results of the response surface are consistent with the experiment and the simulation results. The structures of the compounds were identified by ultra-performance liquid chromatography-tandem mass spectrometry and ultra-performance liquid chromatography-time of flight mass spectrometry.

“…A otimização de um processo de extração visa avaliar as melhores condições de um sistema para extrair determinado analito (Güray, et al, 2020;Nam, et al, 2017). No processo de extração via ultrassom os possíveis parâmetros que influenciam na extração de metabólitos secundários são: concentração da amostra, proporção de solvente, tempo de extração e temperatura (Ghitescu, et al, 2015).…”

Caryocar brasiliense, popularmente conhecido como pequi, é uma espécie que apresenta alto teor de compostos fenólicos com propriedades biológicas. Neste trabalho, o processo de extração assistida por ultrassom, de compostos bioativos das folhas do pequi, foi otimizado com planejamento fatorial Box-Behnken. Quatro variáveis independentes foram avaliadas: concentração da amostra (relação:líquido-sólido (L-S), proporção de etanol na solução (EtOH/H2O % v/v), tempo de EAU (extração assistida por ultrassom) e temperatura. A metodologia de Superfície de Resposta foi usada para apontar a variável mais importante no processo. Os resultados revelaram que a proporção EtOH/H2O (% v/v) tem o efeito mais significante na extração dos compostos fenólicos. A condição ótima para extração foi de etanol 60 %, tempo de EAU de 30 min, temperatura da EAU de 42 °C e L-S 18,7:1. Sob essas condições foram extraídos 6,30 mg EAG/g ES (n = 3) (mg de equivalente de ácido gálico/ g de extrato seco). Os valores experimentais observados confirmam a adequação do modelo empregado e seu sucesso para otimização das condições de extração.
