Hu X, Zhu F, Kong L, Peng X. A novel precipitant for the selective removal of fluoride ion from strongly acidic wastewater: Synthesis, efficiency, and mechanism. JOURNAL OF HAZARDOUS MATERIALS 2021; 403:124039. [PMID: 33265053 DOI: 10.1016/j.jhazmat.2020.124039] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Revised: 08/31/2020] [Accepted: 09/16/2020] [Indexed: 06/12/2023]
Abstract
The strongly acidic wastewater containing fluoride [F(-I)] is generally neutralized using lime, producing massive hazardous solid waste, which may present serious environmental risks. In this study, a novel precipitant, N,N'-Bis(3-(triethoxysilyl)propyl)thiourea, was developed for the selective removal of F(-I) from strongly acidic wastewater. The precipitant was synthesized using (3-aminopropyl)triethoxysilane and thiourea at a molar ratio of 2:1 under 160 ℃. More than 90% of initial F(-I) was removed by the prepared precipitant from strong acidic wastewater produced by nonferrous metal smelting industry, and the residual F(-I) concentration decreased to below 100 mg/L. The F(-I) removal performance is almost free from the interference of coexisting ions. Only 6 kg/m3 of fluoride slag, which can be recycled as a concrete waterproofing agent, was produced. The F(-I) removal mechanism including substitution, polycondensation, ion exchange and complexation was clarified: ‒OH on Si atoms in the hydrolysis product of BTPT was substituted by F(-I), and a fluoro-substituted product formed; the polycondensation of BTPT and fluoro-substituted product produced polymer precipitates; the specific adsorption of F(-I) on the polymer precipitates occurred through ion exchange with ‒OH and complexation with -NH2+-.
