INFRARED SPECTROSCOPY IN THE IDENTIFICATION OF THE CALCIUM CARBONATE LITHIASIS
Figure 1. Multiple kidney stones composed of calcite from a 64-year-old man subjected to lithotripsy. The structure is described as granuloporous, concentric in the nucleus and the trigonal system crystallization. Its composition is 90% calcite, 10% calcium oxalate monohydrate. In the lower, the infrared spectrum of the stone is shown, and at right, the effervescence when it reacts with 0.2M HCl, generating bubbles of CO2 can be observed.
