[Ru(2,2′-bipy)₃]₃(PW₁₂O₄₀)₂ and [Ru(2,2′-bipy)₃]₂(SiW₁₂O₄₀) were synthesized via chemical co-precipitation method using [Ru (2,2′-bipy)₃]Cl₂ and polyoxometalates as reactants. The adsorption ability of absorbents was studied by removing RhB from aqueous solutions in different conditions such absorbent dose, initial dye and contact time. The RPW owns better adsorption ability than the RSI, with a high adsorbing rate of 99% for the RhB under the optimized conditions (10 mg/L, 100 mg, 30 min).
