As we are moving towards the development by urbanization and industrialization on the other hand it is becoming a major environmental impact. Due to the urbanization and industrialization, many processing industries causing major environmental problem, among these problems heavy metal pollution by allowing of industrial waste water into natural water bodies is more dreadful. This is turn increase the heavy metal concentration in natural water bodies resulting in damage to aquatic flora and fauna. The objective of this study is to determine the heavy metal concentration (i.e. Pb) in industrial waste water, in this project waste water from one of the electroplating industries in Bangalore; this study gives knowledge about the percentage removal of lead using lantana camara as an adsorbent. The optimum condition for effective removal of lead is studied by conducting various experiments by varying adsorbent dosage and agitation time and by plotting isotherms, i.e. langmiur isotherms and Freundlich isotherms and pseudo I order and pseudo II order kinematics. This study is carried out using spectrophotometer analysis

Removal Of Metal Ions

: Manuscript discussed about the role of polysaccharides and their derivatives in the removal of metal ions from industrial waste water. Quick modernization and industrialization increases the amount of various heavy metal ions in the environment. They can possess various disease in humans and also causes drastic environmental hazards. In this review the recent advancement for the adsorption of heavy metal ions from waste water by using different methods has been studied. Various natural polymers and their derivatives are act as effective adsorbents for the removal of heavy metal ions from the waste water released from the industries and the treated water released into the environment can decreases the chances of diseases in humans and environmental hazards. From the literature surveys it was concluded that the removal of heavy metal ions from the industrial waste water was important to decrease the environmental pollution and also diseases caused by the heavy metal ions. Graft copolymers were acts as most efficient adsorbent for the removal of heavy metal ions and most of these followed the pseudo first order and pseudo second order model of kinetics.

The objective of this research is to study the potential of using banana peel as a biosorbent in removing heavy metal ions (Cu2+, Zn2+ and Pb2+) and oil/grease particles from industrial waste water. The study emphasizes on the parameters involved in the preparation phase of the banana peel adsorbent, such as particle sizes, activating agent, impregnation ratio, carbonization temperature and duration. Based on the findings, it shows that the adsorption capacity is correlated to the total surface area (SBET), pore volume (VT) and average pore diameter (D) of the materials. Sample A20 yields the highest percentage removal for all tested waste water pollutants, suggesting that banana peel based activated carbon can be used effectively as biosorption material.

Results of taxonomic, arealogical and ecological/biological analysis of aquatic flora of the Belaya River in the area of the city of Sterlitamak, the southern part of Bashkortostan have been presented. In the process of studies of water bodies and watercourses of the Belaya River basin near Sterlitamak 43 species out of 30 genera, 20 families and three divisions of supreme vegetations have been found. Water bodies’ flora of the territory under study is typical for the region and possesses an intra/zonal character. It has been shown that the mineralization degree and industrial waste water discharges of major cities directly affect the supreme aquatic vegetation structure and composition.
