This research is intend to find the kinetics model that appropriate in Pb adsorption process by knowing absorption kinrtika banana peel carbon active within mass variations 1; 1,5 and 2 g and contact time 20, 40, and 60 minutes.

Penelitian ini bertujuan untuk adsoorpsi 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. 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 0, Salah satu 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. Phenol is dangerous substance to a microorganism although in low concentration in wastewater.

Kinetic adsorption was determined using batch adsorption system at various times in several concentrations of procion red.

The way to solve this problem is with used the carbon active from banana peel. The objective of this work was to study the appropriate kinetic model for adsorption dissolved Cr VI in aqueous solution and the kinetic adsorption dependency upon temperature.


Equation which using at the adsorption process are Langmuir and Freundlich isotherm equations. 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. Adsorpsi Pb oleh kulit pisang yang sesuai dengan kinetuka isotherm adsorpsi Langmuir mengindikasikan bahwa adsorpsi hanya berlangsung satu lapis monolayer. How to cite item. 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 Iinetika and economic considerations.

The experiment was carried out in a stirred batch flask. Iron-oxide coated sand was contacted with Cr VI solution at constant temperature. About Adsorpdi Authors Panut Mulyono.

Article Metrics Abstract views: Adsorpsi procion merah pada bentonit dengan berbagai variasi waktu adsorpsi menunjukkan proses adsorpsi satu lapisan pada permukaan bentonit. The data was calculated using Langmuir-Hinshelwood kinetic equation. Abstract Abstrak- Logam Pb merupakan salah satu pencemar lingkungan dan dapat mengakibatkan kematian atau gangguan kesehatan dalam waktu singkat.

From the analysis results, optimum time is at 60 minutes. 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. Adsorption of procion red on natural bentonite adsorlsi studied by kinetic study to know the reactivity of procion red.

Kinetika adsorpsi ditentukan menggunakan sistem adsorpsi simultan pada berbagai waktu dalam beberapa konsentrasi procion merah. Sample was drawn at certain times and the remaining heavy metal concentration was measured by Atomic Absorption Spectrophotometer AAS. Email the author Login required.

Dari hasil analisa, waktu optimum adsorbsi terjadi pada waktu 60 menit. 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 kinetikw with the parameters of operation temperature Tparticle diameter of coconut shell charcoal dand mass ratio of coconut shell charcoal to the solution r.

In this study, coconut shell charcoal is used as the adsorbent. Email this article Login required. Langmuir equation is more appropriate in this research. How to cite item. The empirical rate expression for the adsorption of phenol in aqueous solution with coconut shell charcoal has been determined as: Persamaan adsorppsi Langmuir lebih sesuai untuk isotherm adsorpsi pada penelitian ini.

Data dihitung menggunakan persamaan kinetika Langmuir-Hinshelwood. 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.

Kinetika adsorbsi logam Pb dengan arang 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. The adsorption procion red on bentonite data at various times shows Langmuir kinetikw adsorption kineti,a in the surface of bentonite.

Many adsorbent can be used to adsorp phenol from waste water. 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 kindtika to the material characteristics, the availability this material in Indonesia and economic considerations.

Persamaan yang digunakan dalam proses adsorpsi adalah persamaan adsorpsi Isoterm Langmuir dan Freundlich. Pb absorption from the banana peel that appropriate to Langmuir isotherm system is indicates adsorption was occur in one layer monolayer.
