More information and software credits. Pb absorption from the banana peel that appropriate adsotpsi Langmuir isotherm system is indicates adsorption was occur in one layer monolayer. The way to solve this problem is with used the carbon active from banana peel. Article Metrics Abstract views: The adsorption procion red on bentonite data at various times shows Langmuir monolayer adsorption process in the surface of bentonite.

Iron-oxide coated sand was contacted with Cr VI solution at constant temperature.


How to cite item. 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, Phenol is kinetlka substance to a microorganism although in low concentration in wastewater.


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. 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.

Data dihitung menggunakan persamaan kinetika Langmuir-Hinshelwood. Kinetika adsorbsi logam Pb dengan arang aktif dari kulit pisang pada massa 1 dan 2 g mengikuti model adsirpsi orde 2, sedangkan pada massa 1,5 g mengikuti kinetika orde 0.

Salah satu cara untuk mengatasi masalah adsorpsii Pb adalah dengan menggunakan arang aktif dari kulit pisang. 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. How to cite item. Persamaan adsorpsi Langmuir lebih sesuai untuk isotherm adsorpsi pada penelitian ini. Persamaan adaorpsi digunakan dalam proses adsorpsi adalah persamaan adsorpsi Isoterm Langmuir dan Freundlich.

Many adsorbent can be used to adsorp phenol from waste water. 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. Abstrak- Logam Pb merupakan salah satu pencemar lingkungan dan dapat mengakibatkan kematian atau gangguan kesehatan dalam waktu singkat.

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

From the analysis results, optimum time is at 60 minutes. The empirical rate expression for the adsorption of phenol in aqueous solution with coconut shell charcoal has been determined as: Many adsorption experiments based on equilibrium research and less of them based on kinetics adsorption research. Equation which using at the adsorption process are Langmuir and Freundlich isotherm equations. Kinetika adsorpsi ditentukan menggunakan sistem adsorpsi simultan pada berbagai waktu dalam beberapa konsentrasi procion merah.

Adsorption of procion red on natural bentonite was studied by kinetic study to know the reactivity of procion red. 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.

Langmuir equation is more appropriate in this research. Dari hasil analisa, waktu optimum adsorbsi terjadi pada waktu 60 menit.
