Abstract- Lead metal is one of environment polluter adsirpsi can cause decease or health problems in sort time.


Langmuir equation is more appropriate in this research. About The Authors Panut Mulyono. Email the author Login required. Sample was drawn at certain times and the remaining heavy metal concentration was measured by Atomic Absorption Spectrophotometer AAS.

The experiment was carried out in a stirred batch flask. Persamaan yang digunakan dalam proses adsorpsi adalah persamaan adsorpsi Isoterm Langmuir dan Freundlich. PDF Download 90Kb Abstract Adsorption into iro-oxide coated sand is an interesting alternative for removal of dissolved Cr VI in aqueous solution waste industry due to the material characteristics, the availability this material in Indonesia and economic considerations.

Dari hasil analisa, waktu optimum adsorbsi terjadi pada waktu 60 menit. Email the author Login required. The way to solve this problem is with used the carbon active from banana peel. In this study, coconut shell charcoal is used as the adsorbent. The results showed that the pseudo-first-order model was the most appropriate model for explaining the adsorption of Cr VI solution into iron-oxide coated.

The results also indicated that temperature had significant effect to the rate constant of pseudo-first-order adsorption model k1 and maximum capacity of adsorption qe.

The empirical rate expression for the adsorption of phenol in aqueous solution with coconut shell charcoal has been determined as: Iron-oxide coated sand was contacted with Cr VI solution at constant temperature. The data was calculated using Langmuir-Hinshelwood kinetic equation.

The adsorption rate was found to be increased as the operation temperature and mass ratio increase, but it was decreased as the particle diameter increase. Salah kinstika cara untuk mengatasi masalah pencemaran Pb adalah dengan menggunakan arang aktif dari kulit pisang. Many adsorption experiments based on equilibrium research and less of them based on kinetics adsorption research. One of the most efficient practical method to remove phenol in waste water is adsorption. This research is intend to find the kinetics model that appropriate in Pb adsorption process by knowing absorption of banana peel carbon active within mass variations 1; 1,5 adsrpsi 2 g and contact time 20, 40, and 60 minutes.
