英文摘要	A facile synthesis routine of beta-type strontium hydrogen phosphate (beta-SrHPO4) nanosheets was provided by the method of solution growing at temperatures below 80 degrees C. beta-SrHPO4 was utilized for removing lead ions (Pb2+) and adsorbing methyl blue. Within the pH values from 2.0 to 6.0 of lead solutions, the adsorption capacity of beta-SrHPO4 could reach above 1000 mg.g(-1). The maximum removal capacity was 1409 mg.g(-1) for Pb2+ within 15 min at pH = 4.5 and remained stable with the increase of temperatures. Different cations (Zn2+, Cr3+, Cd2+, and Co2+) affected slightly on the adsorption of Pb2+. It is revealed that the adsorption mechanism of Pb2+ was based on dissolution-precipitation theory. The maximum adsorption capacity was 335.68 mg.g(-1) for methyl blue. The adsorption data of methyl blue accorded with the Langmuir isotherm model with R-2 = 0.994 and the pseudo-second-order kinetic model with R-2 = 0.99996, showing that the removal of methyl blue was dominated by a chemical sorption process. The thermodynamic studies demonstrated that the adsorption process toward methyl blue was endothermic and spontaneous. All of the results showed that beta-SrHPO4 possessed potential applications in removing Pb2+ and methyl blue.
