Removal of dyes using silk nanofiber membranes

Structures of filters for dyestuff removing from waste water should have biocompatibility and low cost, is the main reason to prefer natural materials. Furthermore, high efficiency of the structure to be used for heavy metals removing, the high surface area / volume ratio, and should have high porosity. These features make the nanofibers privileged structures. In this study, silk/nylon-6 elektrospin nanofibriler membranes were obtained by electrospinning method. Blue 49, Violet 1, Black 8 and Orange 13 was used for adsorption studies as a pilot scala. Initial dye concentration, pH and adsorption efficiency of dyes on the surface were determined by spectrophometer. Optimum pH was found 7.0, initial dye concentration was found as 10mg / l (ppm), flow rate was found as 0.1ml/dk.
