Areca Catechu Biochar and Nano-Biochar as Adsorbents for Congo Red: Synthesis, Characterization, and Performance Evaluation

BULLETIN OF CHEMICAL REACTION ENGINEERING AND CATALYSIS, Journal Year: 2025, Volume and Issue: 20(1), P. 112 - 128

The presence of hazardous synthetic dyes such as Congo Red in industrial wastewater poses a significant environmental threat. This study explores the potential biochar (BC) and nano-biochar (nano-BC), derived from Areca catechu husk sustainable adsorbents for dye removal. Nano-BC was synthesised via hydrothermal carbonisation mechanical ball milling, leading to enhanced structural surface properties. X-ray Diffraction (XRD) revealed that Pinang is predominantly amorphous, while BC exhibits increased crystallinity with sharp peaks, nano-BC demonstrates highest nanostructural refinement. Fourier Transform Infra (FTIR) confirmed transformation aliphatic-rich raw biomass into aromatic-dominant structures nano-BC, showing more pronounced graphite-like features. Scanning Electron Microscope (SEM) illustrated morphological evolution, exhibiting refined, uniformly porous structures. BET analysis has significantly higher area 41.38 m²/g smaller pore size 8.4928 nm compared 22.38 15.39 nm, enhancing adsorption capacity. Furthermore, kinetics followed pseudo-second-order model, isothermal monolayer maximum capacity (Qmax = 154.526 mg/g). These findings highlight superior performance emphasising its environmentally friendly water treatment applications.

Advances in Hydrothermal Carbonization for Biomass Wastewater Valorization: Optimizing Nitrogen and Phosphorus Nutrient Management to Enhance Agricultural and Ecological Outcomes

Water, Journal Year: 2025, Volume and Issue: 17(6), P. 800 - 800

Published: March 11, 2025

This study presents a novel approach that integrates hydrothermal carbonization (HTC) technology with circular economy principles to optimize the management of nitrogen and phosphorus in agricultural wastewater. Given increasing global resource scarcity continuous ecological degradation, valorization biomass wastewater has become critical pathway for promotion sustainable development. Biomass wastewater, which contains crop residues, forestry leftovers, food processing byproducts, long been regarded as useless waste. However, this abundant organic matter possesses significant renewable energy potential. The can significantly reduce environmental pollution. Through optimization HTC process parameters, we achieved an improvement quality yield carbonized products, facilitating efficient recycling utilization resources. research demonstrates transform into valuable biofertilizers, energy, feed, while simultaneously reducing reliance on fossil fuels, decreasing greenhouse gas emissions, mitigating impact activities. paper provides comprehensive exploration application ecosystems, highlighting its beneficial role management, efficiency, pollution reduction. findings suggest holds potential optimizing treatment, promoting recycling, advancing Furthermore, offers theoretical support practical guidance implementation is paramount importance fostering economic development achieving agriculture.
