TL;DR
This paper presents a new method using magnetic pistachio shell composites to efficiently remove methylene blue dye from wastewater, turning agricultural waste into a useful resource.
Contribution
The novelty lies in using ball-milled magnetic Fe3O4@pistachio shell composites for high-efficiency dye removal from wastewater.
Findings
The composite achieved 95% methylene blue removal efficiency under optimized conditions.
The adsorbent showed higher selectivity for cationic dyes compared to anionic dyes.
The method is effective for treating industrial wastewater samples.
Abstract
The development of a cost-effective and ecologically beneficial method for removing toxic dye molecules from wastewater is urgently needed for environmental and health reasons. Here, four Fe3O4/PS nanocomposites with different Fe3O4 percentages were fabricated through the mechanochemical technique. This study provided a new monolithic adsorbent from abundant materials via a facile synthetic procedure, which can greatly reduce the problems of the tedious separation of adsorbents from treated waste. The adsorbent is composed of pistachio shell/Fe3O4 composite, which has been used as a highly effective and sustainable adsorbent to eliminate methylene blue (MB) dye under ambient conditions. Diverse characterization analyses, including SEM, EDX, and FTIR techniques, were utilized to investigate the morphology and structure of the synthesized composite. The formed Fe3O4 particles have an…
