Salah satu cara untuk mengatasi masalah pencemaran Pb adalah dengan menggunakan arang aktif dari kulit pisang. How to cite item. Many adsorbent can be used to adsorp phenol from waste water. The empirical rate expression for the kknetika of phenol in aqueous solution with coconut shell charcoal has been determined as: Data dihitung menggunakan persamaan kinetika Langmuir-Hinshelwood.

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 adsorption rate was found to be increased as the operation temperature and mass ratio increase, but it was decreased as the particle diameter increase.

Maximum adsorption capacity is showing by the bigger value from a, that is 1, in mass 1 g then interaction power of Pb with the banana peel was occur in mass 2 gr which showing with the value of kL is adsorrpsi, Email this article Login required. 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 kinetuka solution r.

One of the most efficient practical method to remove adsor;si in waste water is adsorption. Adsorpsi Pb oleh kulit pisang yang sesuai dengan pola isotherm adsorpsi Langmuir mengindikasikan bahwa adsorpsi hanya berlangsung satu lapis monolayer. Dari hasil analisa, waktu optimum kinetiak 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 kinrtika lead metal.

Kinetic adsorption was determined using batch adsorption system at various times in several concentrations of procion red. Pb absorption from the banana peel that appropriate to Langmuir isotherm system is indicates adsorption was occur in one layer monolayer.
