Abstract

As dyes are the most important pollutants of many industrial wastewaters. A large amount of Reactive Black 5 enters the environment in Iran because of the use of this dye in Iran's textile industries, so the goal of this study was to survey the Catalytic Ozonation process with Bone Char in removal of Reactive Black 5 dye from synthetic wastewater. . In this experimental study Bone Char (BC) was prepared under laboratory conditions using of electrical furnace at 800°C for 2h.The prepared BC was crushed and pulverized by standard ASTM sieves at range of 10 to16 mesh. The chemical composition and solid structure of BC was analyzed using X-ray diffraction and measurement of the surface area was carried out by N2 gas adsorption via BET (Brouner Emmet Teller) isotherm. The concentration of dye was measured by photometric method at 600nm wave length. A set with 4 L/min inlet flow rate was used for ozonating to produce 5 gram ozone at hour.. As results showed predominant composition of BC is CaO. The BC surface area is 92.5m2/g. The results of this study showed that increasing of initial dye concentration and pH would lead to decrease of removal of RB5 dye. All of RB5 dye was removed at lapse of 40 minute. . Bone char is a cheap and suitable catalyst that can be used in water and wastewater treatment. Based on optimum pH=10 found for the removal of RB5 and the fact that many of textile industrial wastewaters have an alkaline pH, this process can be suitable for the removal of dyes from these industrial wastewaters. ..
