A novel phosphorus-containing sorbent (CyP(Ph)4-DVB) was prepared by copolymerizing divinylbenzene (DVB) with bis alpha, beta-unsaturated phosphorylated cyclohexene (CyP(Ph)4). Thermogravimetric analysis (TGA) showed improved thermal stability of CyP(Ph)4-DVB compared to poly(DVB). Batch adsorption tests revealed that Freundlich isotherm model provided a better fit for the equilibrium sorption data of C.I. Basic Yellow 2 (BY2) and C.I. Basic Blue 3 (BB3) on CyP(Ph)4-DVB.
A novel phosphorus-containing sorbent (CyP(Ph)4-DVB) was prepared by copolymerizing divinylbenzene (DVB) with bis alpha, beta-unsaturated phosphorylated cyclohexene (CyP(Ph)4). ATR-FT-IR indicated that the phosphinoyl group was introduced into the sorbent structure. The thermal properties of the sorbent were investigated using a differential scanning calorimeter (DSC), which revealed that (CyP(Ph)4-DVB) is more stable than poly(DVB). The CyP(Ph)4-DVB was applied for cationic dye removal, such as C.I. Basic Yellow 2 (BY2) and C.I. Basic Blue 3 (BB3). Batch adsorption tests suggested that the Freundlich isotherm model seemed to be the better one for the description of equilibrium sorption data at equilibrium, rather than the Langmuir or Temkin models. The Freundlich constants concerning the adsorption capacity of CyP(Ph)4-DVB, k(F), were calculated as 14.2 mg(1-1/n)L(1/n)/g for BY2 and 53.7 mg(1-1/n)L(1/n)/g for BB3.
