Removal of fluoride from water using titanium-based adsorbents

Zhijian LI, Shubo DENG, Xueying ZHANG, Wei ZHOU, Jun HUANG, Gang YU

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 4,   Pages 414-420 doi: 10.1007/s11783-010-0241-y

Abstract: Three adsorbents including TiO , Ti-Ce, and Ti-La hybrid oxides were prepared to remove fluoride from aqueous solution. The Ti-Ce and Ti-La hybrid adsorbents obtained by the hydrolysis-precipitation method had much higher sorption capacity for fluoride than the TiO adsorbent prepared through hydrolysis. Rare earth (Ce and La) oxides and TiO exhibited a synergistic effect in the hybrid adsorbents for fluoride sorption. The sorption equilibrium of fluoride on the three adsorbents was achieved within 4 h, and the pseudo-second-order model described the sorption kinetics well. The sorption isotherms fitted the Langmuir model well, and the adsorption capacities of fluoride on the Ti-Ce and Ti-La adsorbents were about 9.6 and 15.1 mg·g , respectively, at the equilibrium fluoride concentration of 1.0 mg·L , much higher than the 1.7 mg·g on the TiO . The sorption capacities of fluoride on the three adsorbents decreased significantly when the solution pH increased from 3 to 9.5. The electrostatic interaction played an important role in fluoride removal by the three adsorbents, and Fourier transform infrared (FTIR) analysis indicated that the hydroxyl groups on the adsorbent surface were involved in fluoride adsorption.

Abstract: Ordered SBA-15 mesoporous silica with incorporated titanium was successfully synthesized via a one-potThe results showed that titanium was successfully incorporated into the mesoporous silica framework witha limited amount of titanium (Si/Ti > 20), and the mesoporous structure was retained.However, the increased titanium content inevitably resulted in the formation of anatase TiO 2titanium strengthened the interactions between cobalt species and supports

Upgrading to urban water system 3.0 through sponge city construction

Nanqi Ren, Qian Wang, Qiuru Wang, Hong Huang, Xiuheng Wang

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 4, doi: 10.1007/s11783-017-0960-4

Abstract: Urban water system 3.0 (Blue, gray, brown and yellow arrows represent water flow, wastewater flow, resource and energy respectively) Facing the pressure of excessive water consumption, high pollution load and rainstorm waterlogging, linear and centralized urban water system, system 2.0, as well as traditional governance measures gradually exposed characters of water-sensitivity, vulnerability and unsustainability, subsequently resulting in a full-blown crisis of water shortage, water pollution and waterlogging. To systematically relieve such crisis, we established healthy urban water-cycling system 3.0, in which decentralized sewerage systems, spongy infrastructures and ecological rivers play critical roles. Through unconventional water resource recycling, whole process control of pollutions and ecological restoration, system 3.0 with integrated management measures, is expected to fit for multiple purposes which involve environmental, ecological, economic and social benefits. With advantages of flexibility, resilience and sustainability, water system 3.0 will show an increasingly powerful vitality in the near future.
