Heavy metal adsorption by graphene oxide modified with 5-amino-3(2-thienyl)pyrazole using central composite design/response surface methodology (CCD/RSM)
5-ATP-GO demonstrated a high adsorption capacity for heavy metals.
The central composite design optimized the adsorption process parameters.
Modified graphene oxide showed significant selectivity for cadmium, mercury, and arsenic.
Response surface methodology confirmed the effectiveness of the adsorption process.
Abstract
A GO-based nano-adsorbent was successfully modified with 5-amino-3(2-thienyl)pyrazole (5-ATP-GO). 5-ATP-GO showed high adsorption capacity and selectivity for Cd, Hg and As.
