The present work aims to evaluate the removal capacity of Rhodamine B dye (RhB) using nano-porous chitosan (NC) from shrimp shells. NC was characterized by XRD, SEM–EDS, N 2 porosimetry, zeta potential (ZP), FTIR, DLS, and zero charge point (pH ZCP ). Compound central rotational design (CCRD) was us...
