SAP Nanomicelle-Functionalized Biochar: A Multifunctional and Sustainable Adsorbent for Efficient Removal of Dyes and Heavy Metals.

ABSTRACT: Herein, a novel multifunctional eco-adsorbent (SMBC) was developed by directly anchoring self-assembled Sapindus saponin (SAP) nanomicelles onto biochar (BC) through a simple and effective method. The resulting material exhibited a significantly enhanced adsorption capacity for p-nitrophenol (PNP), showing a 48.83% improvement compared to unmodified BC. The exceptional adsorption performance for PNP is attributed mainly to polar interactions, π-π interactions, and hydrogen bonding, resulting in a maximum adsorption capacity of 111.21 mg/g. Moreover, SMBC demonstrated high adsorption capacities for cadmium (Cd-(II)), lead (Pb-(II)), methylene blue (MB), and bisphenol A (BPA), reaching 100.17, 104.59, 108.64, and 98.90 mg/g, respectively, surpassing most previously reported adsorbents
