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. Equation which using at the adsorption process are Langmuir and Freundlich isotherm equations. Adsorption into iro-oxide iknetika 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.

Abstract Abstrak- Logam Pb merupakan salah satu pencemar lingkungan dan dapat mengakibatkan kematian atau gangguan kesehatan dalam waktu singkat. Salah satu cara untuk mengatasi masalah pencemaran Pb adalah dengan menggunakan arang aktif dari kulit pisang. 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. Email the author Login required.

Pb absorption from the banana afsorpsi that appropriate to Langmuir isotherm system is indicates adsorption was occur in one layer monolayer. Email the author Login required. Maximum adsorption capacity is showing by the bigger value from a, that is 1, in mass kietika 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, The data was calculated using Langmuir-Hinshelwood kinetic equation.

Abstract- Lead metal is one of environment polluter and can cause decease or health problems in sort time. The way to solve this problem is with used the carbon active from banana peel. Adsrpsi 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.

Phenol is dangerous 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. Post a Comment Login required. The adsorption procion red on bentonite data at various times shows Langmuir monolayer adsorption process in the surface of bentonite.

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.

Adsorpsi procion merah pada bentonit alam telah dipelajari melalui studi kinetik untuk mengetahui reaktivitas procion merah. 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 kietika coconut shell charcoal to the addorpsi r.

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.

One of the most efficient practical method to remove phenol in waste water is adsorption. The empirical rate expression for the adsorption of phenol in aqueous solution with coconut shell charcoal has been determined as: Adsorpsi Kinstika oleh kulit pisang yang sesuai dengan pola isotherm adsorpsi Langmuir mengindikasikan bahwa adsorpsi hanya berlangsung satu lapis monolayer.
