The synthesized resin, crosslinked chitosan serine diacetic acid (CCTS-SDA), showed good adsorption behavior toward trace amounts of Cd, Pb, Cu, Ni, V, Ga, Sc, In, and Th in a wide pH range. Additionally, rare earth elements also can be retained on the resin at neutral pH region. The adsorbed elements can be easily eluted with 1 mol L-1 of nitric acid, and their recoveries were found to be 90-100%. The CCTS-SDA was packed in a mini-column, which was then installed in a cornputer-controlled auto-pretreatment system (Auto-Pret System) for on-line trace elements collection and determination with ICP-AES. Experimental parameters which related to the improvement of sensitivity and reproducibility were optimized. The limits of detection (LOD) for 13 elements were found to be in sub-ppb level. The proposed method with CCTS-SDA resin was successfully applied to the determination of trace elements in river water samples. The method was validated by determining a certified reference material of river water, SLRS-4. en-copyright= kn-copyright= en-aut-name=LukmanHakim en-aut-sei=Lukman en-aut-mei=Hakim kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SabarudinAkhmad en-aut-sei=Sabarudin en-aut-mei=Akhmad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=3 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=2 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=3 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=4 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University en-keyword=chelating resin kn-keyword=chelating resin en-keyword=chitosan kn-keyword=chitosan en-keyword=serine diacetic acid moiety kn-keyword=serine diacetic acid moiety en-keyword=trace elements kn-keyword=trace elements en-keyword=on-line pretreatment kn-keyword=on-line pretreatment en-keyword=computer control kn-keyword=computer control en-keyword=inductively coupled plasma-atomic emission spectrometry kn-keyword=inductively coupled plasma-atomic emission spectrometry en-keyword=SLRS-4 kn-keyword=SLRS-4 END
