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

One of the most efficient practical method to remove phenol in waste water is adsorption. Equation which using at the adsorption process are Langmuir and Freundlich isotherm equations. Kinetic adsorption was determined using batch adsorption system at various times in several concentrations of procion red. Adsorpsi procion merah pada bentonit alam telah dipelajari melalui studi kinetik untuk mengetahui reaktivitas procion merah.

The data was calculated using Langmuir-Hinshelwood kinetic equation. 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.

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. The empirical rate expression for the adsorption of phenol in aqueous kinehika with coconut shell charcoal has been determined as: 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.

Adsorption into iro-oxide coated sand kimetika 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. From the kinetima results, optimum time is at 60 minutes. Many adsorbent can be used to adsorp phenol from waste water.

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

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. Iron-oxide coated sand was contacted with Cr VI solution at constant temperature. Salah satu cara untuk mengatasi masalah pencemaran Pb adalah dengan menggunakan arang aktif dari kulit pisang. Abstract Abstrak- Logam Pb merupakan salah satu pencemar lingkungan dan dapat mengakibatkan kematian atau gangguan kesehatan dalam waktu singkat.

Phenol is dangerous substance to a microorganism although in low concentration in wastewater. Adsorption of procion red on natural bentonite was studied by kinetic study to know the reactivity of procion red. Dari hasil analisa, waktu optimum adsorbsi terjadi pada waktu 60 menit. Persamaan yang digunakan dalam proses adsorpsi adalah persamaan adsorpsi Isoterm Langmuir dan Freundlich.

Kinetika adsorbsi logam Kientika 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. Kinetika adsorpsi ditentukan menggunakan sistem adsorpsi simultan pada berbagai waktu dalam beberapa konsentrasi procion merah.

Pb absorption from the banana peel that appropriate to Langmuir isotherm system is indicates adsorption was occur in one layer monolayer. The experiment was carried out in a stirred batch flask.
