Abstract

powders. Particle gravimetry is used for the quantitative determination of the

dusts. Validation studies are carried out using the ICP-OES technique. The

polymeric fibers prepared with different contents consist of PS/PMMA,

PVDF/EC/PMMA, chitosan, chitosan/PMMA and PMMA/PVDF, respectively.

The ionic liquids of tetra-n-butylammonium tetrafluoroborate,

1-ethyl-3-methylimidazolium hexafluorophosphate and

hexadecyltrimethylammonium bromide are used as additives for the

preparation of the functional polymeric fibers. The prepared nanoscale dusts

and electrospun fibers are characterized by SEM, XRD, XPS, and size

distribution analysis techniques, respectively. Among them, the

CTAB-modified chitosan fibers exhibit the highest dust retention efficiency.

This study introduces a new approach to the quantification of nano-sized

powders. In addition, it is concluded that the proposed method can be used in

pre-concentration before testing, cleaning powders from the working

environment and quantitative analysis of nanoscale powders. The presented

materials can also be used to improve indoor air quality and potential worker exposure in workplaces.
