A series of Yb doped lead oxychloride tellurite glasses with composition of (80-x)TeO2-10PbO-10PbCl2-xYb2O3 were prepared using conventional melt quenching technique. These glasses were then immersed in distilled water (pH 4 and pH 9) for 10 days. The quantitative analysis of Pb2+ and Te4+ were made using induced coupled plasma-mass spectrometer (ICP-MS). The results showed that Te4+ and Pb2+ were highly leached in acidic solution or at lower pH compared to alkaline solution and the addition of Yb3+ in the glass system had reduced or maintained the leaching of Te4+ and Pb2+ from the glasses.

Rigorous Method

Quantitative analysis of the QMCF MD trajectories requires a rigorous method to organize the chaotic data into informative data, clarifying the anisotropy of the hydration structure around the nitrite ion. These results suggested the steric effects of water in the bond directions.

Layer Solution

An aluminum-coated Pyrex® glass rod is used both as a photoacoustic probe and as a laser light guide to examine a three-layer solution of carbon tetrachloride, hexane, and an aqueous solution of an efficient chromophore, ferroin. The boundaries of the layers show up clearly on a signal amplitude vs. penetration depth graph. A Beer's law plot of the ferroin solution alone shows that the probe is capable of analytical determinations down to 10−7 M. Reflections from the cell walls may cause interference in quantitative analysis if the size of the cell is too small. The sensitivity of the probe is compared with that of a typical photoacoustic cell, and it is found that the probe only attenuates the signal amplitude by ∼35%. Finally, it is found that the signal amplitude transmitted by the photoacoustic probe is roughly proportional to its diameter.
