Synthesis of Thiourea-Formaldehyde Resin for Cr3+ Removal

Article Preview

Abstract:

The thiourea (T) -formaldehyde (F) resins with different lamellar crystal structures were synthesized by varying the relative T/F molar ratio in acidic aqueous solution at 55°C. By maintaining the amount of formaldehyde more than that of thiourea, the polymerization reaction allows one to transform the lamellar crystal fragments into cross-linked microspheres, TF resin that has a somewhat high absorption capability to Cr3+.
