How to cite item. 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.

Dari hasil analisa, waktu optimum adsorbsi terjadi pada waktu 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.

About The Authors Panut Mulyono. One of the most efficient practical method to remove phenol in waste water is adsorption. The empirical rate expression for the adsorption of phenol in aqueous solution with coconut shell charcoal has been aesorpsi as: User Username Password Remember me.

Sample was drawn at certain times and the remaining heavy metal concentration was measured by Atomic Absorption Spectrophotometer AAS.

Abstract- Lead metal is one of environment polluter and can cause decease or kknetika problems in sort time. Salah satu cara untuk mengatasi masalah pencemaran Pb adalah dengan menggunakan arang aktif dari kulit pisang.

Equation which using at the adsorption process are Langmuir and Freundlich isotherm equations. 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.

Many adsorbent can be used to adsorp phenol from waste water.

Adsorption of procion red on natural bentonite was studied by kinetic study to know the reactivity of procion red. The way to solve this problem is with used the carbon active from banana peel. Langmuir equation is more appropriate in this research. In this study, coconut shell charcoal is used as the adsorbent.

The experiment was carried out in a stirred batch flask. Abstract Kinegika Logam Pb merupakan salah satu pencemar lingkungan dan dapat mengakibatkan kematian atau gangguan kesehatan dalam waktu singkat. Data dihitung menggunakan persamaan kinetika Langmuir-Hinshelwood.

The adsorption kinetics of phenol in aqueous solution was studied by measuring the concentration of remaining phenol in the solution as a function of time t with the parameters of operation temperature Tparticle diameter of coconut shell charcoal dand mass ratio of coconut shell charcoal to the solution r. Email this article Login required. 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.

Phenol is dangerous substance to a microorganism although in low concentration in wastewater. Adsorption into iro-oxide coated sand is an interesting alternative for removal of dissolved Cr VI in aqueous solution adsor;si industry due to adxorpsi material characteristics, the availability this material in Indonesia and economic considerations.

Kinetika adsorbsi logam Pb dengan kinetkka aktif dari kulit pisang pada massa 1 dan 2 g mengikuti model kinetika orde 2, sedangkan pada massa 1,5 g mengikuti kinetika orde 0.

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

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.
