this study, we used a multimaterial three-dimensional printing
(3DP) technology and porous composite filaments (Lay-Fomm, Gel-Lay,
and Lay-Felt) to fabricate solid phase extraction (SPE) columns for
the enhanced extraction of multiple metal ions. When employed as sample
pretreatment devices in an automatic flow injection analysis/inductively
coupled plasma mass spectrometry (ICP-MS) system, these 3D-printed
SPE columns performed the near-complete extractions of Mn, Co, Ni,
Cu, Zn, Cd, and Pb ions from natural water samples prior to ICP-MS
determination. After optimizing the column fabrication, the extraction
conditions, and the automatic analysis system, the column packed with
the porous composite Lay-Fomm 40 was found to provide the highest
extraction performancethe extraction efficiencies of the listed
metal ions were all greater than 99.2%, and the detection limits of
the method ranged from 0.3 to 6.7 ng L–1. The detection
of these metal ions in several reference materials (CASS-4, SLEW-3,
1640a, and 1643f) validated the reliability of this method; spike
analyses of collected water samples (groundwater, river water, and
seawater) demonstrated the applicability of the method. The nature
of the printing materials enhanced the analytical performance of 3D-printed
sample pretreatment devices. Such approaches will be useful to diversify
the range of sample preparation schemes and analytical methods enabled
by 3DP technologies.
