In order to improve the properties of boron-containing phenol-formaldehyde resin (BPFR), the tetrabromo-bisphenol A epoxy resin (TBBPAER) was used to cure BPFR. The curing mechanism, thermal properties and the fire resistance of TBBPAER/BPFR were investigated by fourier transform infrared spectrometer (FTIR), thermal gravimetric analysis (TGA), torsional braid analysis (TBA) and the oxygen index method. The results show, -OH of -C6H4-CH2OH and -C6H4OH reacts with the epoxy group. With the increase in the amount of BPFR, the thermal properties get better. When the additive amount of TBBPAER is 10 wt%, this material has best thermal stability at high temperature and higher temperature of loss bromine. The glass transition temperature (Tg) is 223.2 °C and the LOI is 68.5.

The paper evaluates the effectiveness of the use of graphene nanostructures in the purification of lead (II) ions to improve the ecological situation of water bodies. The mechanisms and characteristic parameters of the adsorption process were analyzed using empirical models of isotherms at temperatures of 298, 303, 313 and 323 K, which correspond to the following order (based on the correlation coefficient): Langmuir (0.99) > Temkin (0.97) > Dubinin – Radushkevich (0.90). The maximum adsorption capacity of the material corresponds to the range from 230 to 260 mg/g. We research the equilibrium at the level of thermodynamic parameter estimates, which indicates the spontaneity of the process, the endothermic nature and structure change of graphene modified with phenol-formaldehyde resin during the adsorption of lead (II) ions, leading to an increase in the disorder of the system.
