A highly selective ligand exchange type adsorbent was developed for the removal of trace arsenic（V）（As（V）） and phosphate from water. This adsorbent was prepared by loading zirconium（IV） on monophosphonic acid resin. This adsorbent was able to remove toxic anions efficiently at wide pH ranges. However, low pH was preferable for maximum breakthrough capacity in an adsorption operation. The effiect of a large amount of competing anions such as chloride, bicarbonate, and sulfate on the adsorption systems of As（V） and phosphate anions was investigated. The experimental findings revealed that the As（V） and phosphate uptakes were not affiected by these competing anions despite the enhancement of the breakthrough points and total adsorption. Phosphate anion was slightly preferable than As（V） in their competitive adsorption by the adsorbent. The adsorbed As（V） and phosphate on the Zr（IV）-loaded resin were quantitatively eluted with 0.1 mol/L sodium hydroxide solution, and the adsorbent was regenerated by 0.5 mol/L sulfuric acid. During several cycles of adsorption-elution-regeneration operations, no Zr（IV） was detected in the column efiuents. Therefore, the Zr（IV）- loaded monophosphonic acid resin is an efiective ligand exchange adsorbent for removing trace concentrations of As（V） and phosphate from water.

Advances in fabrication of mesoscopic membrane sensors with unique structures and morphologies inside anodic alumina membrane （AAm） nanochannels have led to the development of various methods for detecting, visualizing, adsorbing, filtering, and recovering ultra-trace concentrations of toxic metal ions, such as Hg^2＋ and Pb^2＋, in water and blood. These often ＂one-pot＂ screening methods offer advantages over conventional methods in that they do not require sophisticated instruments or laborious sample preparation. In the present study, we fabricated two mesoscopic membrane sensors for naked-eye detection, recognition, filtration, and recovery of Hg^2＋ and Pb^2＋ in biological and environmental samples. These sensors were characterized by the dense immobilization of organic colorants on the mesopore surfaces of silica nanotubes that were constructed using the nanochannels of an AAm as a scaffold. We confirmed that the nanotubes were oriented along the long axis of the AAm nanochannels, open at both ends, and completely and uniformly filled with organic colorants; also, the dense immobilization of the organic colorants did not affect the speed of ion-to-ligand binding events. We used simple, desk-top, flow-through assays to assess the suitability of the developed membrane sensors for detection, removal, and filtration of Hg^2＋ and Pb^2＋ with respect to recyclability and continuous monitoring. Removal of the target ions from biological fluids was assessed by means of flow cytometric analysis. Our results demonstrate the potential of our membrane sensors to be used for preventing the health risks associated with exposure to toxic metal ions in the environment and blood.
