Abstract: Electrospinning has become a popular method in fiber production due to increased interest in nanofiber technology. It has been an efficient tool to prepare nanofibers for the treatment of waste water. It is a multipurpose, costeffective way of spinning that provides rapid formation of fibers. This study provides an easy and efficient method for the preparation of a novel polyvinyl pyrrolidone titanium oxide (PVPT) composite by electrospinning for the treatment of lead contaminated water. In this purpose, homogeneously distributed TiO powder and TiO included PVP nanofibers were sandwiched into PCL nano fibrous layers. SEM and FTIR analysis were used to witness the synthesis of composite and the morphology of the produced PVPT structures. Average fiber diameter for pure PVP was calculated as 143±35 nm while it was found 114±31 nm for PVPT. Optimum removal was achieved at pH 8; agitation time 30 min, initial concentration of lead solution 10 mg l and adsorbent dosage 50 mg. The kinetics of adsorption was well described by second order kinetic model with the correlation coefficient 0.99. Monolayer adsorption capacity of PVPT was calculated as 33.33 mg g . 2

an oxide on solid support such as polymers [10,11]. In recent years, among polymeric supports, electrospun nanofibers are preferred by scientists in adsorption studies as a result of their high efficiencies and adsorption capacities [12]. The unique properties of electrospun nanofibers render them useful in many applications by bringing enhanced material properties and functionalities. Although there are other methods available in the literature to produce nanofibers such as phase separation, self-assembly, freeze drying, and solvent casting/particulate leaching, electrospinning is accepted as the most simple and efficient one [13-15]. Capability of producing high specific surface area and high porosity mats, simplicity and versatility of the method, cost effectiveness, rapid fiber formation, interconnected porous structure, reproducibility, and capability of continuous fiber formation make electrospinning indisputably preferred method in nanofiber production. On the quality of the end product several factors are affected in electrospun scaffolding which can be categorized under three groups such as polymer solu
