H
emp (Cannabis sativa L.) was used to examine its capability as a renewable resource to decontaminate heavy metals.
Determination of heavy metal content was carried out by means of atomic absorption spectroscopy (AAS). The goal of
this research was to evaluate the attenuation capacity of hemp. The results revealed heavy metals accumulation; cadmium and
chromium in hemp. The analysis consisted of comparing linear, Langmuir and Freundlich isotherms. Langmuir isotherm
resulted in the highest distribution coefficient (Kd) values of 5.6 L/g for Soil to Solution ratio of 1:10. Column testing results
revealed that the concentrations of cadmium dropped from 1.0 to 0.3 mg/L within the first pore volume and by 15 pore
volumes the concentration was close to zero mg/L. This indicated that hemp proved to be an effective adsorbent for the removal
of cadmium ions in water.
