Previous studies of the featured mercury sorbent did not detail the scope and limitations at varying pH and salt concentrations, which are critical to know in remediation projects. This is the first study of the effects of pH and sodium chloride on the rate of mercury uptake by a polymer made from sulfur and limonene. Additionally, the first kinetic model of mercury uptake was established for this material. Finally, leaching experiments under different conditions were completed for the first time, establishing that the sorbent is stable at low and neutral pH, but degrades at pH 11 and releases bound mercury from the bulk sorbent.
