Studying the Adsorption Behavior of Copper Ions in Industrial Wastewater, Using Modified Electrospun Polymeric Nano Fiber
Journal Title: Archives of Hygiene Sciences - Year 2016, Vol 5, Issue 4
Abstract
Background & Aims of the Study: Soil and water pollution to heavy metals is a serious threat for environment and human health. Finding an effective way for refining water from these metals is very important. The aim of this study was modifying electrospun polymeric nano fibers and studying its efficiency for copper ion omission in water solutions. Materials & Methods: In this study, nano fiber was produced by solution electrospun polystyrene in DMF/THF solvent and produced nano fiber was used for copper pre-concentration in waste water sample. In this study, an investigation of primary PH of solution, adsorption particle size, cleaning solvent volume, salt supply, contact time duration of adsorption material on copper ion adsorption supply was done, using modified nano 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, pH optimized amount for isolating copper ion on absorbent level is 7, absorbent particle size is 0.006 g/l, salt 1.3, potassium nitrate and the contact time of absorbent material on copper ion 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 and measuring. The mean of the method was 2.7 µg/l and standard deviation was lower than %4. Conclusions: this method was done on actual samples which findings show that, this method has the ability of cooper adsorption and can use this method for measuring heavy metals like copper in different tissues. This method because of having the privilege for isolating and pre concentrating different kind of mineral and organic is used successfully in different samples.
