Abstract

In this research, a study of adsorption kinetics of heavy metal ions on the Ulva pertusa and Hizakia fusiformis which is aiming at removing metal ions from water or every kind has been carried out. During the process of this research. Adsorption kinetics of Cd(II) and Pb(II) ions by the Ulva pertusa and Hizakia fusiformis, within five minutes reached at the maximum adsorption amount. The adsorption amoum by Ulva pertusa was more than the other. Adsorption ratio by Ulva pertusa were 15.0~100% of Cd(II) and 39.2~82.5% of Pb(II). Adsorption ratio by the Hizakia fusiformis were 18.3~100% of Cd(II) and 56.4~94.7% of Pb(II). Additionally, recovery ratio or Cd(II) from the Ulva pertusa presents 75.0~83.6% and that of Pb(II) ions presents 79.1~85.5%. Also, recovery ratio of Cd(II) from Hizakia fusiformis fusiformis were 66.7~85.0% of Cd(II) ions and 77.6~83.9% of Pb(II) ions respectively. As a result of this research. adsorption amount of Cd(II) and Pb(II) ions by Ulva pertusa was more than it by Hizakia fusiformis.
