Naema S. Yehia, Sayed S. El-Sherfy, Rehab A. Salam


Dissolution rates of calcium oxalate monohydrate (COM) were studied in the presence of Furosemide (Fm) and Hydrothiazide (Hz). Experiments were carried out at pH=6.5, t= 37 ºC, ionic strength =0.15 and degree of under-saturation (?) = 0.09. The results revealed that the inhibition followed surface controlled mechanism. The retardation effect followed the sequence Fm? Hz.
