Considerable interest has been paid to laser-induced breakdown in liquid because of its wide application to medical issues of the eye and environmental monitoring. Therefore, the present work aims to study the phenomena of LIB in bulk distilled water generated in laser-induced breakdown spectroscopy (LIBS) experiment. The effect of experimental parameters such as inter-pulse delay between the two lasers, laser pulse energy and detection time window have been studied to examine the temporal growth of the laser-induced plasma in bulk water. Electron density and plasma temperature have been determined. The Stark broadening profile has been utilized for the electron density determination where the hydrogen lines $H_{\unicode[STIX]{x1D6FC}}$ and $H_{\unicode[STIX]{x1D6FD}}$ have been used. A deviation between electron density values from the broadening of both lines has been observed and discussed. The electron density values are varied between $10\text{E}+18$ and $10\text{E}+17~\text{cm}^{-3}$ corresponding to the timing experimental parameters. The plasma temperature is varied over a range 16 000 $\text{K}$ to 10 700 $\text{K}$ due to the plasma’s temporal behaviour with experimental parameters.

Laser-induced breakdown spectroscopy (LIBS) has been applied for quantitative analysis of Al 2 O 3 , CaCO 3 and MgO particles suspended in water. In the single elemental system, the plasma emission intensities of Al, Ca and Mg were linearly increased with concentration of elements in the range of 1.0·10 À5 -1.0·10 À3 M, 1.0·10 À4 -2.0·10 À3 M and 8.0·10 À5 -4.0·10 À3 M, respectively. We also investigated the concentration dependence of breakdown spectra for suspended mixtures of Al 2 O 3 , CaCO 3 and MgO particles. The emission lines, such as Al I, Ca I, Ca II and Mg I, were appeared in the LIBS spectrum simultaneously, and each emission peak could be deconvoluted. The plasma emission intensities of Al, Ca and Mg in the multielemental system were also linearly increased with their concentrations in the range of 1.0·10 À5 -1.0·10 À3 M, 1.0·10 À4 -2.0·10 À3 M and 4.0·10 À4 -2.0·10 À3 M, respectively. LIBS was found to be available for quantitative and qualitative measurement of the concentrations of Al 2 O 3 , CaCO 3 and MgO particles suspended in water. The present results suggest that LIBS is a potentially useful tool for in-situ analysis on particles composition and concentrations for environmental monitoring by the wearable information equipments.

Laser-induced breakdown spectroscopy / Europium / Eu 2 O 3 suspension / Precipitation / SorptionSummary. The generation of Eu(III) precipitation and the Eu sorption on TiO 2 particles in aqueous solution were studied using laser-induced breakdown spectroscopy (LIBS). The plasma emission intensity vs. the Eu concentration plot showed a good linearity in the concentration range of 6.6 × 10 −3 M − 1.3 × 10 −2 M for Eu aqueous solution at pH 1.1 and 6.6 × 10 −5 M − 6.6 × 10 −4 M for Eu 2 O 3 suspension at pH 5.0. It was found that the generation of Eu precipitation was detected through a drastic increase of plasma emission intensity of Eu. The results suggested that LIBS is useful for analyzing the particles and the precipitation of Eu in aqueous solution, even if the Eu ion concentration is higher by orders of magnitude. Furthermore, we could measure the plasma emission of Eu ions sorbed on TiO 2 particles under the conditions where the plasma emission of Eu ions could not be detected in the absence of TiO 2 . Hence, LIBS technique is considered to be useful to study the colloid generation of Eu.
