About

Ademir dos Santos has made impactful contributions to environmental analytical chemistry, with a focus on developing automated methods for trace metal determination. His key research areas include flow-injection analysis, atomic absorption spectrometry, and the monitoring of heavy metals in complex environmental matrices. His most notable work, "Reversible intermittent flow-injection determination of mercury in sediments and vinasses by cold vapor atomic absorption spectrometry" (1999), introduced an innovative reversible intermittent flow-injection procedure that automated mercury detection in challenging samples like sediments and vinasses. By employing air-carried streams of sample and stannous chloride, his method enhanced sensitivity and reproducibility while reducing reagent consumption and waste. This approach has been cited 2 times, reflecting its specialized utility in environmental monitoring. Dos Santos’s work addresses critical needs in assessing mercury contamination in industrial and natural ecosystems, particularly in regions impacted by sugarcane vinasse disposal. His contributions exemplify the integration of flow-based automation with atomic spectrometry, offering practical solutions for routine environmental analysis. His research continues to inform best practices in trace element analysis and pollution control.
