|Title:||ADSORPTION OF BENZALDEHYDE FROM WASTEWATER|
|Authors:||Rajoriya, Ravi Kumar|
|Abstract:||The deterioration of ttroter quality started with fast industrialization and globalization. Untreated discharges from domestic and industrial activities resources and urban agglomerate into water bodies are the main sources of both punitively and qualitatively. Water is a fundamental component of the earth's cco-system and ensures a rich diversity of plant and animal life. Its quality affects biota-flora and fauna. Water resources need to be conserved and their quality should be preserved. Industrial wastewater is the discharge of industrial plants and manufacturing processes. The impact of industrial discharges depends not only on their collective characteristics. such as biochemical oxygen demand and the amount of suspended solids. but also on their contents of specific organic and inorganic substances. Amongst many pollutants affecting water quality arc mining, petroleum processing, chemical and petrochemical units, steel and metal smelter plants, pulp and paper mills, textile, caustic, chlorine production units and agriculture industries. Benzaldehyde is an aromatic aldehyde used in the rood. beverage, pharmaceutical, perfume, soap, and dyestuff industries. Benzaldehydc occurs as a constituent of oils of hitter almond, peach and apricot kernel. It is usually prepared synthetically. It is a colorless liquid having an odour resembling that of bitter almond oil, and a burning taste. It is affected by light and it oxidizes in air to benzoic acid. Activated carbons are high porosity, high surface area materials used in industry for purification and chemical recovery operations as well as environmental remediat ion. Present study deals with equilibrium and kinetic modeling for the adsorptive removal of benzaldeb:,,rde using granular activated carbon. Optimum conditions for benzaldehyde removal were found to be adsorbent dose of 4 WI found Ibr activated carbon. Equilibrium time was achieved 4 h. Equilibrium adsorption data was analyzed by Freundlich, Langmuir and Temkin isotherm equations, using regression and error analysis. Freundlich isotherm was found to best represent the data for benzaldellyde adsorption for activated carbon.|
