Preparation and Characterization of Attapulgite Modified by KH-570 for Formaldehyde Adsorption

Abstract:

Modification of attapulgite by KH-570 for formaldehyde adsorption and characterization of the resulting sorbents by SEM, BET, FT-IR and TG-DSC were conducted, as well as the test of the breakthrough curves of formaldehyde dynamic adsorption. The results show that KH570 was grafted with the surface silanol group of attapulgite. The adsorption capacity of attapulgite for formaldehyde was improved significantly by KH-570, which has a certain utility to remove the formaldehyde gas in the air.
