This study aims to investigate the effect of alkalization and chemical coupling methods on the surface
and adsorption properties of waste cotton and cotton/polyester yarns. The simple and cheap alkali treatment was
performed using 10% and 18% NaOH solution, while the chemical coupling method involved combining cotton
and cotton/polyester yarns and fly ash, using sodium carboxymethyl cellulose and sodium alginate as binders.
Morphological and surface characteristics of unmodified and modified cotton and cotton/polyester yarns were
analyzed by scanning electron microscopy and Fourier transform infrared spectroscopy, while adsorption properties were assessed by the removal of lead and cadmium ions from aqueous solution. It was found that chemical
modification with 18% NaOH solution positively affected the adsorption properties of only cotton yarns, increasing the removal efficiency of lead ions up to 75%. On the other hand, modification with fly ash improves the adsorption propertie...s of both, cotton and cotton/polyester yarns, increasing the efficiency in removing lead ions by
using sodium carboxymethyl cellulose, and cadmium ions by using alginate as a binder. Using the chemical coupling method, effective adsorbents are obtained starting from waste yarn, which gives it added value, the amount
of non-degradable waste material can be reduced and the criteria of a cleaner environment and circular economy
can be met.
