Abstract

Water pollution and plastic accumulation pose significant environmental challenges that demand innovative solutions. In this work, we upcycled polystyrene foam waste (PSW) and incorporated it with chromium metal–organic frameworks (MOF-Cr) by electrospinning to develop nanofiber composite adsorbent for toxic organic dyes. Various characterization techniques have proven the incorporation of MOF-Cr into the mats of the prepared PSW NFs. A parametric study was undertaken to analyze the impact of pH, contact time, initial concentration, and temperature on the adsorption performance. The Langmuir and pseudo-second-order model provide the most appropriate fitting of the adsorption behavior with a maximum adsorption capacity of 354.49 mg/g for the MOF-Cr@PSW NFs compared to 86.61 mg/g for PSW NFs at 35 °C. The recycling experiment showcased the exceptional selectivity and reusability of MOF-Cr@PSW NFs. This study presents a novel approach to tackling both the challenges of dye-polluted water and plastic waste accumulation in the environment.

期刊介绍： Chemical engineering enables the transformation of natural resources and energy into useful products for society. It draws on and applies natural sciences, mathematics and economics, and has developed fundamental engineering science that underpins the discipline. Chemical Engineering Science (CES) has been publishing papers on the fundamentals of chemical engineering since 1951. CES is the platform where the most significant advances in the discipline have ever since been published. Chemical Engineering Science has accompanied and sustained chemical engineering through its development into the vibrant and broad scientific discipline it is today.
