Simplex-Centroid mixture design applied to arsenic (V) removal from waters using synthetic minerals

Recent Applications of Mixture Designs in Beverages, Foods, and Pharmaceutical Health: A Systematic Review and Meta-Analysis

“…Table 5 presents a subdivision of the MDs' possible applications that can be used within the area, and these subdivisions were classified as applications related to the area: animal, bioenergy, biology, and materials. [29,30,[187][188][189][190][191] According to Table 5, MD research in bioenergy aims to optimize biodiesel synthesis from a blend of five different oils [181]; investigate the effects of cellulose, xylan, and lignin constituents on biomass pyrolysis characteristics and bio-oil composition [177]; production of biomethane using municipal sludge wastes, grease trap waste, and meat processing waste [179]; investigate the ability of the oleaginous yeast Debaryomyces etchellsii strain for lipid production for biodiesel manufacture using different agro-industrial wastewaters (cheese whey, expired soft drinks and fresh olive mill) as substrates [175]; investigate the effect of light wavelength on Dunaliella salina to increase microalgae lipid productivity for biodiesel production [176]; optimization of viscosity and density of refined palm oil-Melaleuca Cajuputi oil binary blends for a novel biofuel [180]; formulation of a vermicomposting in organic matters with dairy manure vermicompost, straw, and peat using MDs in cucumber seedling experiment to evaluate the compressed substrates [183]; optimization of concentrations of the solvents ethanol, acetone and water in the extraction of total phenolics present in cashew apple bagasse [178] and optimization of a method for the determination of metals from palm oil by flame atomic absorption spectrometry [182].…”

“…For the materials area, MDs have been used in glass formulation using iron phosphate base glass system that contained P 2 O 5 , Fe 2 O 3 , Al 2 O 3 , Na 2 O, and SO 3 [29]; hydraulic oil formulation with different materials based on specific restrictions applying multiresponse optimization [189]; analysis of the effects of nano-oil additives (using ZnO, Si 3 N 4 and carbon nanotubes) on the wear properties of AISI 4140 steel material [190]; formulate and examine the mechanical properties of cotton shell particles integrated into glass-fiberreinforced polymer composites [187]; optimization of bitumen formulations using asphaltic residue, vacuum residue, and three aromatic extracts (by-products) from the refining process of base oils [188]; formulation of alkali-activated cement mortars incorporating glass powder, slag, and calcium aluminate cement [30]; and investigate the arsenic (V) removal from waters using synthetic minerals using synthetic poorly crystallized aluminum hydroxide, calcined layered double hydroxide, and two-line ferrihydrite [191].…”

Adsorption and desorption of arsenic and its immobilization in soils

“…On the other hand, comparing the soils P1 and P5, which present the same proportion of clay (68 %) and similar adsorption capacity, we observed that the sample P1, with a mineralogy that was more gibbsitic, presented desorption of the element at a considerably lower rate, reaching a difference of 50 % using phosphate as an extractor. Studies reported in the literature (Lin and Puls, 2000;Zhang et al, 2011;Dias et al, 2019) mention that Al-hydroxides have a high specific surface. Dias et al (2019) observed that adsorbents with higher values for specific surfaces have the highest adsorption capacity values.…”

“…Adsorption/desorption of As is the main factor that impacts As mobility in soils (Zhang and Selim, 2005). These adsorption and desorption balances are controlled by the mineral and organic matrices of soils (Dias et al, 2019). Many studies have sought to clarify the role of minerals, soils, and sediments in the retention and release of As into the environment (Ladeira and Ciminelli, 2004;Zhang and Selim, 2005;Mello et al, 2006;Borba et al, 2017;Dias et al, 2019;Fontes et al, 2019).…”

Knowing the types of interaction involved makes it possible to predict the destination of As in relation to potential environmental changes (Zhang and Selim, 2005).…”
