Abstract

Milk is considered to be a complete food an disconsumed by individuals of all age groups. Urea is added to milk as an adulterant to increase its shelf life and Solid Not Fat (SNF) value. Excess urea consumption is harmful to human beings which results in serious health issues. Hence, there is an utmost necessity of an instrument to detect and quantify the presence of urea content in milk. ZnO nano powder was synthesized using Sol-Gel process and it was coated on a glass substrate in the form of thick film using the Doctor Blade method. The ZnO immobilized with urease enzyme was used as a sensing layer for detection of urea in milk. The fabricated sensor has a sensitivity of 0.6mV/10mg and the designed instrument indicates the presence of urea within the permissible range by corresponding LED.

用氧化锌纳米颗粒制作尿素传感器,设计便携式牛奶中尿素电子检测仪器
牛奶被认为是一种完全的食物,所有年龄组的人都不食用。在牛奶中添加尿素作为掺假剂,以延长其保质期和固体非脂肪(SNF)值。过量的尿素消耗对人体有害,会导致严重的健康问题。因此,非常需要一种仪器来检测和量化牛奶中尿素含量的存在。采用溶胶-凝胶法制备ZnO纳米粉体,并采用Doctor Blade法将其涂覆在玻璃基板上形成厚膜。采用脲酶固定化氧化锌作为检测牛奶中尿素的传感层。所制备的传感器灵敏度为0.6mV/10mg,所设计的仪器通过相应的LED指示尿素在允许范围内的存在。
