Reaction Steps

A suspension of calcium phosphate was prepared by introducing 100 mg of CDA into 8.75 ml of ultrapure water mixed with 1.25 ml of a 0.02 mol.l−1 sodium alendronate aqueous solution. The suspension was placed in a tube maintained at room temperature, and was stirred with a rotary stirrer at 16 rpm for 5 days. The suspension was then centrifuged and the most part of the supernatant was removed. The solid residue was filtered off, washed several times with small portions of ultrapure water, and then dried at room temperature. The resulting solid contained 7.4 wt % alendronate.
