- •
A novel way for synthesizing water-soluble thiourea-formaldehyde resin was proposed.
- •
The resin decreased effectively the leaching concentrations of Cr, Pb and Cd.
- •
Melamine can effectively decrease the content of free formaldehyde in the resin.
- •
The structure was characterized by elemental analysis and FTIR spectra.
