“…For the first 30 minutes, the adsorption was approximately 37% and gradually increased with an increase in time until the 90th minute ( Figure 5), and then levelled off after 120 minutes. Similar behaviour was reported by Aliabadi et al [10] for the removal of different metal ions using electrospun PEO/chitosan nanofibres. They found that the equilibration time was 120 minutes.…”

“…Chitosan has excellent biocompatibility, biodegradable properties, nontoxicity and ease of solubility in organic acids [1]. However, electrospinning of pure chitosan has some constraints, such as difficult to form continuous fiber jets during electrospinning due to the repulsive forces between the ionic groups and high surface tension of the polymer solution because high viscosity of chitosan even in moderate concentration [7].…”

“…The nanofibers prepared by electrospinning method have many advantages such as very large surface area-to-volume ratio, high porosity with very small pore size and malleability to produce different morphologies [1,2].Due to these advantages, electrospun nanofibers have widely beeninvestigated in the past years with materials of different composition for biomedical, sensors, filter media, electrochemical energy storage and other industrial applications [2,3,4,5,6]. …”

Abstract. Electrospun nanofibers have many advantages such as high porosity, easy to be fabricated in various size and high ratio of surface area to volume. This paper presents the preparation of electrospun PVA/Chitosan nanofibers and more specifically focuses on the effect of post-treatment on the permeability and morphology of electrospun PVA/chitosan nanofibers. The mixtures of various concentrations of PVA (6,7,8 wt%)and 2 wt%.chitosan solution (with the ratio of 3:1)were used in electrospun with a constant rate of 0.7 ml/hour. The post-treatment was conducted by immersing in a ethanol or glutaraldehyde solution to performed crosslink structure. The electrospun PVA/Chitosan nanofiber was characterized by scanning electron microscopy (SEM) and fourier transform infrared (FTIR) spectroscopy. The results revealed that the viscosity of the mixture solution is directly proportional to its concentration. Increasing the viscosity increased the diameter of fiber but also made the larger beads formation. FTIR measurement exhibited the existence of relevant functional groups of both PVA and chitosan in the composites.The crosslinked structure was found for the electrospun PVA/Chitosan nanofibers treated with glutaraldehyde solution.

“…Determination of cadmium trace elements in water is still one of the tedious job in analytical chemistry and it requires highly sensitive and accurate analytical methods [3]. Various methods based on solvent extraction [4], ion exchange [5], membrane filtration [6], cloud point extraction [7][8][9], coprecipitation [10,11] and solid phase extraction [12,13] have been developed for the pre-concentration of trace elements in water samples.…”

In this study, the flotation technology was used to separate and enrich the heavy metal Cd 2+ ions. Based on literature, it was found that Cd 2+ could form CdI4 2-with KI in solution and then (RhB)2(CdI4) was occurred when CdI4 2-was mixed with rhodamine B. This ternary associate was determined by bisolvent of ester and ionic liquid flotation system. Ionic liquid was [Bmim]BF4, the optimal amount of acetic acid, potassium iodide and rhodamine B was 8, 20 and 4 mL, respectively. The best removal efficiency obtained at a flotation time of 15 min with air flow rate of 30 mL/min and 38 % mass fraction of (NH4)2SO4 solution was 95.68 %. The experimental data indicated that the ionic liquid have more excellent function than the traditional organic solvents.
