• 論文の詳細を見る

• An urease immobilizing membrane was prepared by ultrafiltrating a mixture consisted of quarternized chitosan, sodium polyacrylate and urease in an aqueous NaBr solution. Permeation and hydrolysis characteristics of aqueous urea solutions through the urease immobilizing membrane was kinetically investigated under various conditions. A rate of hydrolysis of urea through the urease immobilizing membrane corresponded to the Michaelis-Menten type reaction. Kinetic data for the hydrolysis of urea through this membrane were discussed by comparing with those for the hydrolysis of urea in a batch reaction using native urease.
