The present experimentation is carried out with albizia lebbeck leaves for removal of dyes using Iron nano particles. The operating parameters involved are contact time, pH, initial concentration, dosage of nano particle solution and temperature. The dyes studied are Congo red and Crystal violet. The characterization studies involved are FTIR and XRD. The optimum pH is 5 for crystal violet using albizia lebbeck nano particle solution. The equilibrium contact time obtained is 40 min. Similar trend also followed for Congo red dye. The positive attributes confirmed that albizia lebbeck leaves broth along with iron chloride formed iron nano particles and are capable of removing crystal violet and congo red dyes Index Terms—Dyes, pH, concentration, temperature, dosage, FTIR and XRD. I. INTRODUCTION Textile industry effluents are highly toxic not only to humans but even microorganisms and plant species. These dyes in water stop the passage of sunlight to roots of the plants and sustainability of microorganisms. Hence these dyes from industries are to be pretreated before leaving them on to earth’s surface. As there are several methods for pretreatment yet none of them are ecofriendly and free from chemicals. Hence search for alternate methods has risen and sought the attention towards nano technology. Hence the present study is focused on removal of dyes using nano particles. The present experimentation is designed in such a way that the operating parameters like contact time, pH, concentration, dosage and temperature will be optimized along with the confirmation through characterization using FTIR and XRD. II. EXPERIMENTAL PROCEDURE The present experimentation is carried out in batch process for removal of dyes (congo red and crystal violet) from synthetic solutions by using albizia lebbeck leaves broth with iron nano particles (al-fe-nps). Analytical grade chemicals were used for experimentation and need no further purification. Double distilled water is used to prepare all stock and synthetic solutions. From a stock solution containing 1000 mg of dyes in 1.0 litre, the synthetic solutions of dyes were made. By addition of O.l M HCl and O.l M NaOH solutions the pH of dyes solutions were adjusted to the desired value. Fig. 1 Dyes Fig. 2 Dyes stock solutions(a)Congo Red(b)Crystal Violet Dr. CH. A. I.
