Persamaan adsorpsi Langmuir lebih sesuai untuk isotherm adsorpsi pada penelitian ini. Abstract- Lead metal is one of environment polluter and can cause decease or health problems in sort time. How to cite item. Many adsorbent can be used to adsorp phenol from waste water. Adsorpsi procion merah pada bentonit alam telah dipelajari melalui studi kinetik untuk mengetahui reaktivitas procion merah.

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

The adsorption procion red adsorpi bentonite data at various times shows Langmuir monolayer adsorption process in the surface of bentonite. The way to solve this problem is with used the carbon active from banana peel. Adsorpsi procion merah pada bentonit dengan berbagai variasi waktu adsorpsi menunjukkan proses adsorpsi satu lapisan pada permukaan bentonit.

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. From the analysis results, optimum time is at 60 minutes.

Abstrak- Logam Pb kinefika salah satu pencemar lingkungan dan dapat mengakibatkan kematian atau gangguan kesehatan dalam waktu singkat.

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

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