Excellent Cr(vi) adsorbent made from pyrolyzed green coconut trash with parametric modelling and optimization using RSM and experimental data

Abstract

Surface characteristics of coconut biochar before and after adsorption.

Polyethyleneimine-functionalized β-cyclodextrin porous polymers for enhanced elimination of U(vi) from wastewater

“…Besides, the R r value of PEI-PCDP for U( vi ) gradually entered the plateau phase when the SD increased from 0.2 g L −1 to 0.3 g L −1 , which might be ascribed to the existence of the adsorption limit value of PEI-PCDP conformed to the general rule of heavy metal ions adsorbed by materials. 49 Considering the economics, 0.2 g L −1 was selected for subsequent adsorption tests.…”
