用玻璃布作为固定化酶的载体,以戊二醛为交联剂,把脲酶固定在这种载体上而制成固定化脲酶膜电极;同时,研究了这种电极的响应时间、恢复时间、尿素浓度线性范围、最低检测限以及温度和PH值对电极响应的影响。
Using glass cloth as immobilized enzyme carrier and glutaraldehyde as crosslinker, urease was immobilized on this carrier to make immobilized urease membrane electrode. At the same time, the response time, recovery time, The linear range of urea concentration, the lowest detection limit, and the effect of temperature and pH on electrode response.
