The objective of this work was to study the appropriate kinetic model for adsorption dissolved Cr VI in aqueous solution and adsirpsi kinetic adsorption dependency upon temperature.

Many adsorption experiments based on equilibrium research and less of them based on kinetics adsorption research.

Iron-oxide coated sand was contacted with Cr VI solution at constant temperature. 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. Email this article Login required.

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. More information and software credits. 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.

Kinetika adsorpsi ditentukan menggunakan sistem adsorpsi simultan pada berbagai waktu dalam beberapa konsentrasi procion merah. User Username Password Remember me.


Kinetkka data was calculated using Langmuir-Hinshelwood kinetic equation. Data dihitung menggunakan persamaan kinetika Langmuir-Hinshelwood. Maximum adsorption capacity is showing by the bigger value from a, that is 1, in mass 1 g knetika interaction power of Pb with the banana peel was occur in mass 2 gr which showing with the value of kL is 0, The way to solve this problem is with used the carbon active from banana peel.

Sample was drawn at certain times and the remaining heavy metal concentration was measured by Atomic Absorption Spectrophotometer AAS. Phenol is dangerous substance to a microorganism although in low concentration in wastewater. The results showed kinftika the pseudo-first-order model was the most appropriate model for explaining the adsorption of Cr VI solution into iron-oxide coated. Abstract- Lead metal is one of environment polluter and can cause decease or health problems in sort time.

Article Metrics Abstract views: Langmuir equation is more appropriate in this research.

Equation which using at the adsorption process are Langmuir and Freundlich isotherm equations. One of the most efficient practical method to remove phenol in waste water is adsorption. Persamaan adsorpsi Langmuir lebih sesuai untuk isotherm adsorpsi pada penelitian ini. User Username Iinetika Remember me. The experiment was carried out in a stirred batch flask.

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. Adsorpsi procion merah pada bentonit dengan berbagai variasi waktu adsorpsi menunjukkan proses adsorpsi satu lapisan pada permukaan bentonit.

Many adsorbent can be used to adsorp phenol from waste water. How to cite item. Persamaan yang digunakan dalam proses adsorpsi adalah persamaan adsorpsi Isoterm Langmuir dan Freundlich.

Dari hasil analisa, waktu optimum adsorbsi terjadi pada waktu 60 menit. Post a Comment Login required.

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. Adsorption into kinetia 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 Indonesia and economic considerations.
