 ABSTRACT The present investigation has been so designed as to provide some insight on various aspects of adsorption power of carbon materials.Inthis investigation we use various types of charcoal of approaximately same particle  size, namely activated charcoal ,wood charcoal, coconut shell charcoal, paddy shell charcoal and studied  their power using oxalic acid as adsorbate. INTRODUCTION        In recent years research in the field of adsorbents and adsorption has gained considerable importance because of its wide applications. Activated charcoal is used as adsorbent in gas masks in which al toxic gases and vapors are adsorbed by the charcoal and pure air is passed through it. Silica and alumina gel are used as adsorbents for removing moisture and for controlling humidity in closed bottles ,bottles, boxes and rooms. Adsorption also plays an important role in heterogeneous catalysis. For example the role of finely divided iron in the manufacture ...
