Abstract
56.2% of Aldrich HA was recovered from water by XAD-8 and AGMP-50 procedure. With this method, 0.58mg/l of HA was determined in the water collected from irrigation reservoir near Tae Dok Science Town. For the removal of ash from Aldrich HA, centrifugation was simple, but as effective as dialysis. Neither centrifugation nor dialysis removed Na at all. Only with XAD-8 and AGMP-50 procedure, Na and ash were completely removed.
