Herein, effective removal of brilliant green dye from the water was achieved using eco-friendly and sustainable adsorbent (CHA/RP-CA) derived chitosan (CHA) functionalised rambutan (Nephelium lappaceum L.) peel carboxylic acid (citric acid, CA). Using Box-Behnken Design (BBD), adsorption variables, A: CHA/RP-CA dosage (0.02–0.08 g), B: pH (4–10), C: contact duration (10–40 min), were modelled optimised. The BBD model's results showed that ideal variables for maximum BG (93.68%) ~ 10, dose = 0.066 g, 39 min. Pseudo-first-order Freundlich models agreed with experimental by CHA/RP-CA. With an capacity 439.5 mg/g CHA/RP-CA, created biomaterial demonstrated a strong ability to adsorb BG. Several interactions, including Yoshida H-bonding, electrostatic, n-π, are involved in cationic process on This study encourages development adsorbents waste biomass biopolymers effectively removing dyes wastewater. Multiple Sustainable Development Goals (SDGs) met current endeavour, SDG 6 (Clean Water Sanitation), 12 (Responsible Consumption Production), 13 (Climate Action), 14 (Life Below Water).
