ABSTRACT:
A novel technique has been discovered for separating oxalate from urine and other biological fluids. The method involves mixing the fluid with an adsorbent to separate the oxalate from the fluids, washing the adsorbent-oxalate complex, and releasing the oxalate by reacting the complex with alkali. This technique provides accurate results and can easily be run in hospitals and clinical laboratories.
