A drug dispensing system for water quality detection based on spectrophotometry

Since the advent of industrialization, environmental pollution has become increasingly severe. Ensuring the ecological safety of water bodies and human health has made water quality testing an important means. Spectrophotometry, a commonly used water quality analysis method, boasts high sensitivity and simple operation. However, the many dangerous reagents involved in spectrophotometry pose significant risks to human health. Traditional manual dispensing methods are time-consuming, labor-intensive, and prone to errors, making it difficult to meet the efficiency and accuracy standards of modern environmental monitoring. Moreover, traditional manual handling and contact with toxic substances fail to ensure the safety of experimenters. This paper proposes and studies an automatic water quality testing dispensing system based on spectrophotometry. The system perfectly integrates the spectrophotometric testing system, automatic dispensing system, and artificial intelligence robot system to enhance testing efficiency, experimental safety, and accuracy. Through this system, reagents can be automatically formulated and accurately transported, allowing for the rapid and precise determination of the COD value of polluted water. Experimental results indicate that the system improves detection efficiency by at least 30% compared to traditional methods, while also reducing human error rates.
