Biomass trans-Anethole-Based Hollow Polymer Particles: Preparation and Application as Sustainable Absorbent

Abstract

A novel type of hollow polymer particles containing carboxyl groups was prepared from a widely available biophenylpropene trans-anethole (ANE). To prepare the hollow particles, we first prepared polymeric particles using vinyl acetate and maleic anhydride (MAH), and then such particles were taken as sacrificial templates for the subsequent formation of core/shell particles, which were synthesized by using ANE and MAH as comonomers and divinylbenzene (DVB) as cross-linking agent through precipitation polymerization. After removing the core in the prepared core/shell particles, we obtained hollow particles and then hydrolyzed the anhydride groups into carboxyl functional groups. The hollow particles were characterized by FT-IR, SEM, and TEM, and further used as absorbents. The maximum adsorption toward Cu 2+ and methylene blue reached 270 and 940 mg/g, respectively. The recycling study showed that the biobased hollow particles can be easily restored and reused. The hollow particles may find practical applications as sustainable absorbents. The established methodology for preparing hollow polymer particles is expected to be applicable for other biophenylpropenes.

Biomass‐Derived Acetylenic Polymer Monoliths Prepared by High Internal Phase Emulsion Template Method and Used for Adsorbing Cationic Pollutants

“…MB concentration of the supernatant was determined by measuring the UV–vis absorbance and calculated based on a working curve. The amount of the adsorbed MB at equilibration state ( q e , mg g −1 ) was calculated by the following equation: [ 36 ] where C 0 (mg L −1 ) is the initial MB concentration, and C e (mg L −1 ) is the MB concentration at equilibration state. m (g) is the mass of PolyHIPE‐Na + and V (L) is the volume of MB aqueous solution.…”

“…Langmuir and Freundlich isotherm models applied for the present study are, respectively, expressed in the following equations: [ 36 ] where q m and K L are Langmuir constants related to maximum adsorption capacity and binding energy, respectively; K f (L mg −1 ) and n are empirical constants that indicate the Freundlich constant and heterogeneity factor, respectively.…”

“…Pseudo first order model and pseudo second order kinetic model were expressed in the following equations: [ 36 ] where q e (mg g −1 ) and q t (mg g −1 ) are the adsorption capacity at equilibration state and at time t , k 1 (min −1 ) and k 2 (g mg −1 min −1 ) are the rate constant of pseudo first order model and the rate constant of pseudo second order.…”

pH-Responsive Hollow Polymeric Microspheres from Irradiated Cyclic Ether Aqueous Solution

“…Stimuli-responsive hollow particles, especially hollow micro-sized or nano-sized spheres, continue to attract major interest because they have wide potential applications in fields such as dye precipitation [1], catalysis [2,3], sensors [4][5][6], and especially controlled delivery systems [7][8][9][10]. Early studies on hollow polymeric microspheres were conducted by Caruso et al [11].…”
