However, the fermented broth contains a complex mixture of impurities, residual sugars, and phenolic compounds that impair polyol purity and require selective removal. This study investigated six adsorbent materials with distinct physicochemical properties for their ability to selectively purify polyol-rich broth via multicomponent adsorption. Activated carbons (acidic, basic, and neutral), a synthetic resin (Sepabeads SP700), and two ion-exchange resins (Diaion HPA512L and UBK550) were evaluated. pH variation (3−9) showed negligible influence on adsorption, allowing neutral conditions (pH 7) for subsequent tests. Among the materials, acid-activated carbon and HPA512L resin demonstrated superior clarification performance while preserving the polyol content. Kinetic studies fitted the pseudo-second-order model (R2 = 0.93−1.00), indicating chemisorption. Adsorption equilibrium data were best described by Extended and Modified Langmuir isotherms (R2 > 0.991), evidencing competitive adsorption between polyols. Acid-activated carbon showed the highest adsorption capacities, while the HPA512L resin offered operational benefits at elevated temperatures. These findings provide a foundation for designing efficient and sustainable downstream processes for polyol purification from biomass hydrolysates.  \n■ INTRODUCTION  \nCocoa pod husk biomass (CPH), a byproduct generated in large quantities during the processing of cocoa beans, represents a promising source of lignocellulosic materials.1 Globally, cocoa is widely cultivated for the production of chocolate and derivatives, reaching 4.84 million tons expected for the year 2024/2025.2 In Brazil, the sixth largest producer in the world, cocoa production grew significantly, reaching more than 296 thousand tons in 2023, representing a value of more than 800 million dollars, an increase of 12.69% compared to the previous year.3  \nWithout proper use, the indiscriminate disposal of CPH can lead to soil contamination and the proliferation of pests, which directly affect the cultivation of this fruit.1 Although often underutilized, this biomass contains a series of components of industrial interest, such as cellulose, hemicellulose, and phenolic compounds, making it a potential raw material for several biotechnological applications.4 The valorization of CPH represents not only an opportunity to add value to agricultural residues but also a concrete strategy to promote more sustainable practices in the agrifood sector. This aligns with the principles of the circular economy and biorefinery and contributes directly to multiple United Nations Sustainable  \nDevelopment Goals (SDGs), particularly SDG 9 (Industry, Innovation and Infrastructure), SDG 12 (Responsible Consumption and Production), and SDG 13 (Climate Action). Therefore, this matrix can drive sustainability, support waste valorization, and reduce environmental impacts associated with agroindustrial processes.5  \nThe hemicellulose fraction of CPH can be used to produce polyols of great industrial interest such as arabitol and xylitol. This process can occur biotechnologically through pentose fermenting microorganisms.6,7 The polyols arabitol and xylitol are ","cbCaivF0Nerw79Jf","https://ap.wps.com/l/cbCaivF0Nerw79Jf","pdf",7720109,17,"English","# Abstract\n# Introduction\n## Cocoa pod husk as a lignocellulosic feedstock\n## Polyol production and purification challenge\n# Adsorption approach and materials\n# Results: pH effect, performance, kinetics, and isotherms\n# Implications for downstream processing","[{\"question\":\"Why is selective removal of contaminants necessary in polyol-rich fermented broth?\",\"answer\":\"Fermented broth contains impurities, residual sugars, and phenolic compounds that impair polyol purity.
