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 and 2 g and contact time 20, 40, and 60 minutes.

Sample was drawn at certain times and the remaining heavy metal concentration was measured by Atomic Absorption Spectrophotometer AAS. Penelitian ini bertujuan untuk menentukan model kinetika yang sesuai pada proses adsorpsi Pb dengan melihat daya jerap arang aktif kulit pisang dalam berbagai variasi massa 1 g; 1,5g dan 2 g dan waktu kontak 20 menit, 40 menit dan 60 menit. Kinetics analysis are based from orde zero,one, and two and find the maximum capacity of adsorption from banana peel carbon active to lead metal.

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.

KINETIKA ADSORPSI LOGAM BERAT Cr(VI) DENGAN ADSORBEN PASIR YANG DILAPISI BESI OKSIDA

Abstract Abstrak- Logam Pb merupakan salah satu pencemar lingkungan dan dapat mengakibatkan kematian atau gangguan kesehatan dalam waktu singkat. How to cite item.

Data dihitung menggunakan persamaan kinetika Langmuir-Hinshelwood. Persamaan yang digunakan dalam proses adsorpsi adalah persamaan adsorpsi Isoterm Langmuir dan Freundlich.

Abstrak- Logam Pb merupakan salah satu pencemar lingkungan dan dapat mengakibatkan kematian atau gangguan kesehatan dalam waktu singkat. User Username Password Remember me. Email the author Login required. Many adsorption experiments based on equilibrium research and less of them based on kinetics adsorption research.

Langmuir equation is more appropriate in this research. Pb absorption from the banana peel that appropriate to Langmuir isotherm system is indicates adsorption was occur in one layer monolayer.

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. Email this article Login required.
