Abstract: A novel fluorescent dye based on naphthalimide has been synthesized from 4-bromo-1,8-naphthalic anhydride. This compound was reacted with N-ethylglycinate and buthylenediamine, respectively. Purification of products was carried out through recrystalization and characterized by means of FTIR, 1HNMR and 13CNMR spectroscopic techniques. The maximum absorption wavelength, extinction coefficient and fluorescent spectra of the dye together with quantum yield have been evaluated in DMF and toluene solvents. Results showed that the synthesized dye has positive solvatochromism effect and good color strength in yellow hue. This dye was grafted to the chain of a polymer leading to colored fluorescent polymer. In this study novel polymer with naphthalimide pendant group were prepared. The ability of the dye for grafting to polymer chain was demonstrated that 95% dye incorporated in to the polymer chain.

Abstract: Many metropolitan cities in India including the city of Hyderabad have experienced a very fast rate of urbanization and phenomenal growth of population in the past few decades. The high density of population had resulted in development of many housing colonies, industrial, commercial and institutional building complexes without matching growth in necessary infrastructure such as protected water supply, underground sewerage system and solid waste management. In this process, many of the lakes in the urban areas had given way for water quality deterioration and the lakes still surviving, in the process of urbanization are polluted by discharge of wastewater, storm water, solid wastes and other unauthorized inputs. These problems exist all over the world and especially in the developing and underdeveloped countries. In fact the standards of sanitation and management of liquid and solid waste in an urban area can be judged from the water quality status of lakes in the area. A highly pollut
