Lead sorption constants in organoclay, activated carbon, apatite, and freshwater sediment
Research Mentor(s)
Sofield, Ruth M.
Description
Lead is one of many metals that is known to cause toxicological harm to aquatic organisms at environmentally relevant concentrations. Historically lead has been released to the aquatic environment through industrial, consumer, and gasoline products. Within the aquatic environment sediment typically sorbs lead and other metals, which reduces the bioavailability to aquatic organisms. Our experiment is a benchtop scale determination of sorption constants (Kd) between lead spiked water and four different sorbents (sediment, activated carbon, apatite, organoclay). The experimental goal is to produce sorption constants (Kd) for different treatments and compare the lead binding abilities of each treatment. The use of each treatment is applicable to large scale sediment remediation projects and will be useful in comparing which treatment will be best to use in remediating lead pollution.
