“…CAs are typically produced from materials such as wood pulps or cotton, which contain highly pure cellulose, but are rather expensive (Cao et al 2018). Therefore, in the past decades, researchers focused their efforts toward the preparation of CAs from less expensive lignocellulosic biomasses, including corn fiber, rice hulls, and wheat straw (Biswas et al 2006), rice husk (Das et al 2014), agave bagasse (Soto-Salcido et al 2018), sugarcane bagasse (Candido et al 2017;Nakanishi et al 2011), newspaper paper and mango seeds (Meireles et al 2010), and Pinus sp. sawdust (Ballinas-Casarrubias et al 2015).…”

Waste biomass (agave bagasse) and native birch wood were used as raw materials for a novel fractionation and derivation process to produce cellulose acetates (CAs). During the first stage of the fractionation process, a significant amount of hemicelluloses and lignin were dissolved from the biomass using a natural deep eutectic solvent (NADES) that consisted of a mixture of choline chloride and lactic acid with the molar ratio of 1:9. Then, the residual solid material was delignified by bleaching it with a mixture of acetic acid and sodium chlorite. The fractionation process generated differently purified pulps (celluloses) which were converted to CAs. The crystallinity index, polymerization degree, chemical composition, and thermal properties of the differently purified pulps and CAs were analyzed to evaluate the efficacy of the acetylation process and to characterize the CAs. The chemical derivation of the differently purified cellulose samples generated CAs with different degrees of substitution (DSs). The more purified the cellulose sample was, the higher its DS was. Moreover, some differences were observed between the acetylation efficiencies of birch and agave bagasse. Typically, cellulose purified from birch by treating it with NADES followed by bleaching was acetylated more completely (DS = 2.94) than that derived from agave bagasse (DS = 2.45). These results revealed that using green solvents, such as NADES, to treat both agave bagasse (waste biomass) and birch wood, allowed pure fractions to be obtained from biomass, and thus, biomass could be valorized into products such as CAs, which present a wide range of applications.

“…A full factorial and an extreme vertices mixture designs with a centroid were constructed to achieve three primary objectives: 1) adequately probe the dependence of treatment factors via elimination of confounding due to aliasing in other design options, 2) obtain an acceptable level of assessment of the experimental variance, and 3) result in an appropriate characterization of the response surface as an initial step toward full exploration of identified surface using other response surface methods. Additionally, factorial designs are often used as an efficient tool to narrow the important factors associated with membrane formation and performance 38,39 . The factorial design addresses the case of using ratios rather than weight percentages for the system components.…”

“…Additionally, factorial designs are often used as an efficient tool to narrow the important factors associated with membrane formation and performance. 38,39 The factorial design addresses the case of using ratios rather than weight percentages for the system components. Using ratios essentially circumvents the dependency constraint inherent in weight and/or mole fractions compositions.…”

Mixed matrix membranes (MMMs) are effective materials for emerging separation applications. While MMMs show promise, various membrane formation schemes have produced particle agglomerations, surface ruptures, and varying separation performance as a result. In this work, a replicated 2 × 23 full factorial design of experiment (DOE) and a mixture analysis was conducted to investigate the effects of activated carbon, polyethylene glycol (PEG), and solvent type, used during MMM formation. Aniline blue filtration was used as a model for performance. A thorough analysis was conducted on contact angle, agglomeration frequency, water flux, and dye rejection. Specifically, a novel and facile method to study agglomeration tendencies is presented. Among other trends, agglomeration tendencies were mitigated by the addition of PEG during the fabrication process. Water flux increased from 10 to 55 LMH when PEG was used as a pore former and dye rejection increased from 72% to 90% with the addition of AC particles.

“…Soto‐Salcido et al (2018) research was focused on the preparation, characterization, and performance of acetylated cellulignin membranes manufactured from agave bagasse obtained at maximal cellulose recovery further acelyted by Fischer process. The membranes were produced by the evaporation precipitation method, and the resulting membranes were characterized by SEM, AFM, FITR, TGA, and DMA, comparing a CTA membrane obtained in the same conditions.…”
