Analysis of Aqueous Solutions by Laser-Induced Breakdown Spectroscopy of Ion Exchange Membranes

Abstract: Elemental analysis of solutions can be achieved by concentrating and immobilizing the metal ions into a commercially available ion exchange polymer membrane followed by laser-induced breakdown spectroscopy. Two methods of sample preparation were investigated: filtering the solution through the ion exchange membrane with suction, and placing the membrane in the solution and allowing the ions to equilibrate with the membrane. The membrane was then ablated with the focused energy of a Nd:YAG laser at 1064 nm. The… Show more

“…Impurity enrichment can also be realized electrochemically Xiong et al 2010) for certain species; the normal practice is to use a highpurity inert electrode and apply a DC voltage to reduce or oxidize the ionic species in water to form a solid layer. Other impurity enrichment methods include using ion exchange membranes as reported by Schmidt and Goode (2002) and by Kim et al (2010) for Cu detection. Wood and bamboo have also been used as substrates; Zhu et al (2012), Jiang et al (2011), andChen et al (2010) pretreated the aqueous samples by immersing wood or bamboo chips in liquids followed by drying.…”

“…Table 3 compares the detection limits of the proposed method with those obtained by combining an IED with ICP-AES [12,13], ICP-MS [14], LIBS [15], or XRF spectrometry [17,18] for the determination of heavy metals in water. The detection limits of the proposed method are lower than those of LIBS and comparable to those of XRF spectrometry.…”

“…Several direct analysis methods combining an IED with Laser-Induced Breakdown Spectroscopy (LIBS) [15,16] or X-ray fluorescence (XRF) spectrometry [17,18] have been reported for the determination of heavy metals in water. Direct introduction/AAS [19] is also attractive.…”

“…Rapid chemical analysis of liquids by LIBS [9] has many potential applications; among them, there are monitoring of waters [10][11][12][13], of quality in pharmaceutical or food industry [14][15][16], medical diagnostics [17,18], and control of industrial processes or mechanical equipment [19,20]. Laser-induced plasma on or inside liquids generates intense shockwaves, bubbling, and expulsion of droplets, which together with the laser energy losses due to liquid vaporization reduce the available energy for the plasma excitation.…”

“…Excluding some complex methods for preparation of liquid samples that eliminate advantages of LIBS in terms of simplicity, rapidity, and possibility for in-field measurements, on evaporating liquids (like waters and alcohols), an intense LIBS signal could be obtained by probing the residues left on a solid substrate [13,14,18,23]. The sample drying should be performed close to room temperature in order to prevent losses of volatile components.…”
