Adsorpsi procion merah pada bentonit alam telah dipelajari melalui studi kinetik untuk mengetahui reaktivitas procion merah. User Username Password Remember me. Kinetic adsorption was determined using batch adsorption system at various times in several concentrations of procion red. About The Authors Panut Mulyono. How to cite item. Sample was drawn at certain times and the remaining heavy metal concentration was measured by Atomic Absorption Spectrophotometer AAS. Adsirpsi 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 kimetika.

Dari hasil analisa, waktu optimum adsorbsi terjadi pada waktu 60 menit. 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. Persamaan adsorpsi Langmuir lebih sesuai untuk isotherm adsorpsi pada penelitian ini.

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

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

The experiment was carried out in a stirred batch flask.

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, 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 adsirpsi g and contact time 20, 40, and 60 minutes.

One of adsorpsl most efficient practical method to remove phenol in waste water is adsorption. More information and software credits. The results showed that the pseudo-first-order model adaorpsi the most appropriate model for explaining the adsorption of Cr VI solution into iron-oxide coated.

Adsorpsi Pb oleh kulit pisang yang sesuai dengan pola isotherm adsorpsi Langmuir mengindikasikan bahwa adsorpsi hanya berlangsung satu lapis monolayer. Abstrak- Logam Pb merupakan salah satu pencemar lingkungan dan dapat mengakibatkan kematian atau gangguan kesehatan dalam waktu singkat.

The way to solve this problem is with used the carbon active from banana peel.

Phenol is dangerous substance to a microorganism although in low concentration in wastewater.

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.

Many adsorption experiments based on equilibrium research and less of them based on kinetics adsorption research. Many adsorbent can be used to adsorp phenol from waste water.

In this study, coconut shell charcoal is used as the adsorbent.

The data was calculated using Langmuir-Hinshelwood kinetic equation. Langmuir equation is more appropriate in this research.
