Abstrak- Logam Pb merupakan salah satu pencemar kinetuka dan dapat mengakibatkan kematian atau gangguan kesehatan dalam waktu singkat. 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 Indonesia and economic considerations. 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 addorpsi ratio of coconut shell charcoal to the solution r.

Sample was drawn at certain times and the remaining heavy metal concentration was measured by Atomic Absorption Spectrophotometer AAS. Kinetika adsorpsi ditentukan menggunakan sistem adsorpsi simultan pada berbagai waktu dalam beberapa konsentrasi procion merah. Adsorpsi procion merah pada bentonit dengan berbagai variasi waktu adsorpsi menunjukkan proses adsorpsi satu lapisan pada permukaan bentonit.

Persamaan adsorpsi Langmuir lebih sesuai untuk isotherm adsorpsi pada penelitian ini. Email the author Login required.

The adsorption procion red on bentonite data at various times shows Langmuir monolayer adsorption process in the surface of bentonite.

Dari hasil analisa, waktu optimum adsorbsi terjadi pada waktu 60 menit. Many adsorbent can be used to adsorp phenol from waste water.

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. From the analysis results, optimum time is at 60 minutes. More information and software credits. The experiment was carried out in a stirred batch flask. One of the most efficient practical method to remove phenol in waste water is adsorption.

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

About The Authors Panut Mulyono. Langmuir equation is more appropriate in this research. Data dihitung menggunakan persamaan kinetika Langmuir-Hinshelwood.


Iron-oxide coated sand was contacted with Cr VI solution at constant temperature. Adsorption of procion red on natural bentonite was studied by kinetic study to know the reactivity of procion red.


Persamaan yang digunakan dalam proses adsorpsi adalah persamaan adsorpsi Isoterm Langmuir dan Freundlich. 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. 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 alam telah dipelajari melalui studi kinetik untuk mengetahui reaktivitas procion merah. This research is intend to find the kinetics model that appropriate in Pb adsorption process by knowing absorption of banana peel carbon active within kunetika variations 1; 1,5 and 2 g and contact time 20, 40, and 60 minutes.

In this study, coconut shell charcoal is used as the adsorbent. 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. 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 dangerous substance to a microorganism although in low concentration in wastewater.
