Application of the technique of biosorption by a plant sorbent in thetreatment of chemical releases from a hospital laboratory

The present study aims to investigate the treatment of chemical releases of laboratories Bacteriology of the hospitals. Generally, the waste can be treated with thermal, chemical, biological, and physical processes, but these methods are expensive and sometimes can‘t be supported by the small industry sector thereby prohibits the use of these techniques and consequently leads the non-treatment of liquid waste from this sector. Thereby to reduce the cost of treatment of industrial effluents, more research is oriented towards the use of available and inexpensive products such as clays, products and agricultural by-products, forestry or food, hence the use of the bark of eucalyptus in this study.
