Studying the Adsorption Behavior of Copper Ions in Industrial Wastewater, Using Modified Electrospun Polymeric Nano Fiber

Background & Aims of the Study: Soil and water pollution to heavy metals is a seriousthreat for environment and human health. Finding an effective way for refining water fromthese metals is very important. The aim of this study was modifying electrospun polymericnano fibers and studying its efficiency for copper ion omission in water solutions.Materials & Methods: In this study, nano fiber was produced by solution electrospunpolystyrene in DMF/THF solvent and produced nano fiber was used for copper preconcentrationin waste water sample. In this study, an investigation of primary PH ofsolution, adsorption particle size, cleaning solvent volume, salt supply, contact timeduration of adsorption material on copper ion adsorption supply was done, using modifiednano fiber.Results: According to this study, copper adsorption process with correlation coefficient of(R2) in scope of 0.986 by Langmuir and Freundlich are describable. Findings show that, pHoptimized amount for isolating copper ion on absorbent level is 7, absorbent particle size is0.006 g/l, salt 1.3, potassium nitrate and the contact time of absorbent material on copperion adsorption is 10 minutes. Copper ion adsorbate was cleaned, using 0.7 ml methanol.Most of obtrusive ions didn t have any inconvenience for copper ion isolation andmeasuring. The mean of the method was 2.7 μg/l and standard deviation was lower than4%.Conclusions: this method was done on actual samples which findings show that, thismethod has the ability of cooper adsorption and can use this method for measuring heavymetals like copper in different tissues. This method because of having the privilege forisolating and pre concentrating different kind of mineral and organic is used successfully indifferent samples.
