STUDY ON REMOVAL OF CADMIUM FROM WATER ENVIRONMENT BY ADSORPTION ON GAC, BAC AND BIOFILTER



INTRODUCTION

Cadmium is introduced in to bodies of water from smelting, metal plating, Cadmium-Nickel batteries, phosphate fertilizer, mining, pigments, stabilizers, alloy industries and sewage sludge. The harmful effects of Cadmium include a number of acute and chronic disorders, such as itai-itai disease, renal damage, emphysema, hypertension, and testicular atrophy (1).

Engineering Design Methods of Adsorption Systems

Introduction

Understanding of engineering design methods of adsorption systems is
an important aspect of process engineering design not only in the
chemical industry but also in the fields of environmental pollution control
and energy utilization. Moreover, adsorption is coming to be regarded as
a practicable separation method for purification or bulk separation in
newly developed material production processes of, for example, high-tech
materials and bioc ....etc

INTRODUCTION

Adsorption refrigeration system uses adsorbent beds to adsorb and desorb a refrigerant to obtain cooling effect.

Adsorption systems mainly use a natural working fluid which have zero ozone depletion potential.

However, the adsorption cooling machines still have some disadvantages that hinder their wide application.

Inventors propose technologies to improve adsorption system and make it become a realistic ....etc

The adsorption of large molecules, such as proteins and colloids, from solution to solid surfaces is often dominated by steric exclusion of molecules already present on the surface. This talk will review some theoretical approaches to the quantitative description of the adsorption kinetics. In particular, I will describe the Random Sequential Adsorption (RSA) theory for irreversible adsorption and experimental studies that demonstrate its accuracy. I will also present recent work on the reversible binding of macromolecules on heterogeneous surf ....etc

Cadmium is a chemical element with symbol Cd and atomic number 48. This soft, bluish-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than other transition metals. Cadmium and its congeners are not always considered transition metals, in that they do not have partly filled d or f electron shells in the elemental or common oxidation states. The average concentration of cadmium in Ea ....etc

Adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface. This process creates a film of the adsorbate on the surface of the adsorbent. This process differs from absorption, in which a fluid (the absorbate) is dissolved by or permeates a liquid or solid (the absorbent), respectively. Adsorption is a surface-based process while absorption involves the whole volume of the material. The term sorption encompasses both processes, while desorption is the reverse of it. Adsorption is a surface pheno ....etc
