The Effects of pH on Microfluidics Flow Characteristics of Heavy Metals

Abstract

This paper describes a flow experiment and characteristics of heavy metals based on microfluidics, in order to improve the prefabricated vertical drain system that is possible pollutants removal and soil improvement in soft ground polluted with various pollutants, simultaneously. The result showed that the surface with hydrophobic condition affected large effect on flow velocity pollutants, and pH condition was also influence factor for change of flow velocity. Especially, the flow velocity of lead has risen slightly, when pH was close to basicity in complex heavy metal. This means that lead pollutant can reduce a hydrophobic characteristic in comparison with a copper pollutant.

Permeable Reactive Barrier Remediation Technique Using Carbonized Food Waste in Ground Contaminated with Combined Cu and Pb

“…Without appropriate pretreatment, the discharge of these pollutants poses severe environmental and health risks [3][4][5]. The complexity of predicting the dispersion of these contaminants in soil and groundwater further exacerbates the challenge of remediation, rendering the restoration of affected areas particularly daunting [6]. The presence of heavy metals such as lead and copper in the soil not only complicates natural remediation efforts but also poses direct and indirect threats to human health and ecosystems [7][8][9][10].…”
