Abstract

Titration is a method used in laboratories to determine the concentration of a titrate. The auto-titrator is a commercial apparatus that carries out the titration operation automatically and provides the equivalence point data. The Automated titrator follows a defined sequence of operations which are repeated several times until the endpoint of the titration reaction is reached (titration cycle). Commercially available auto-titrators are typically expensive and cost approximately Rs.60,000 and above. A miniaturised micro-volume autotitrator with potentiometric end-point detection is proposed. The method is based on on-line potentiometric titration of the acids with various bases. The main purpose of the project is to develop a low powered system with sufficient accuracy for educational applications at a cost of about one-fifth of the commercially available systems.
使用pH值端点检测的低功率自动滴定仪
滴定法是实验室中测定滴定物浓度的一种方法。自动滴定仪是一种自动进行滴定操作并提供等当点数据的商用仪器。自动滴定仪按照规定的操作顺序重复几次,直到达到滴定反应的终点(滴定周期)。市售自动滴定器通常价格昂贵,价格约为60,000卢比或以上。提出了一种具有电位终点检测功能的小型化微体积自动滴定仪。该方法是基于在线电位滴定法与各种碱的酸。该项目的主要目的是开发一种低功耗系统,具有足够的准确性,用于教育应用,成本约为商用系统的五分之一。
