The sensors for fast-determination of L-ascorbic acid have been made by immobilizing ascorbate oxidase on cellophane membranes and mounting the enzymic membranes on Clark onygen electrodes and new methods of purifying of L-ascorbate oxidase from the peel of cucumber and immobilizing it. The response of the electrodes is linear between 10 and 1000mg/dl ascorbic acid and the precision is better than 0.79% by 20 successive assays. The responsing time is less than 20 seconds. The enzymic membrane was made up of three layers, a basic layer, an enzymic layer and an endolayer. And its lifetime is more than 3 weeks. After preparation, buffer of phosphate is the only reagent needed. The sensor involved two parts, the preliminary appearance and the second. The prelimin ary appearance was made of enzyme electrode, actor, a system of phos phate buffer. involving a mirco-pump and a vibrational agitator. And the second, two series magnifying of signal and dealing with the signal as well as function and a system of data display controlling by a computer were involoved.

Chitin is the most aboundant naturally occurring amino polysaccharide. Chitosan is the N—deacetylated product of chitin. They have recently begun to attract much attention in both basic and applied research fields, including not only biology and biochemisty, but also organic and polymer chemistry, pharmacology and medicine. Among some unique properties of chitin and chitosan, their utilization as film / membrane materials seems to be one of the most attractive and promising functions. They have been used as membrane materials for ultrafiltration, reverse osmosis, pervaporation, ion exchange, enzyme immobilizing and biomedicine (suture, wound dressing and hemostatic sponge etc.). Their preparations and applications have been reviewed indetail.
