Abstract
- In this study, flexible polyurethane foam (FPUF) was successfully coated with nano-Mg(OH)2 platelets. Due to the strong interaction between chitosan and nano-Mg(OH)2, it was possible to yield modified foam with a weight-gain of up to 15 wt% by depositing one chitosan layer and one nano-Mg(OH)2 layer. Meanwhile, the adsorption isotherms of Cu2+ on FPUF covered with 10 wt% coating (FPUF-10) shows the Langmuir behavior. It was found that for the FPUF-10, the removal % for Cu2+ after 30 min and 50 min treatment were 86% and 90%, respectively. Moreover, the maximum removal % could reach up to 95%.
