Recent research in chitosan-based electro spun nanofibers has led to the very cost-effective and efficient removal of toxic metal ions from solutions that are extremely important in today’s pollution-ridden world. Nanofiber fabrication of chitosan blends can easily be done by the novel electrospinning technique. Because of their high adsorption capability, metal chelation ability, nontoxicity, biocompatibility, biodegradability, hydrophilicity, and cost effectiveness, chitosan-based nanofibers have seen rapid growth in water treatment applications. This review outlines the ability of electrospinning produced chitosan-based nanofibers to remove toxic metals. The primary goal of this review is to provide current information on various chitosan blend nanofibers that may be useful in water purification, as well as to encourage further research in this area.</p></abstract><trans-abstract xml:lang="ru"><p>Хитозан – перспективный экологически чистый полимер с широким спектром применения в биологической, медицинской и водоочистной областях. Недавние исследования электроформованных нановолокон на основе хитозана показали возможность очень экономичного и эффективного удаления ионов токсичных металлов из растворов, что чрезвычайно важно в современном загрязненном мире. Изготовление нановолокон из смесей хитозана может быть осуществлено с помощью нового метода электропрядения. Из-за высокой адсорбционной способности, способности хелатировать металлы, нетоксичности, биосовместимости, биоразлагаемости, гидрофильности и экономической эффективности нановолокна на основе хитозана быстро находят применение в области очистки воды. В этом обзоре описывается способность нановолокон на основе хитозана, полученных электропрядением, удалять токсичные металлы. Основная цель этого обзора – предоставить текущую информацию о различных нановолокнах из смеси хитозана, которые могут быть полезны для очистки воды, а также стимулировать дальнейшие исследования в этой области.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хитозан</kwd><kwd>электроформование</kwd><kwd>нановолокна</kwd><kwd>удаление токсичных металлов</kwd><kwd>очистка воды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Chitosan</kwd><kwd>electrospinning</kwd><kwd>nanofibers</kwd><kwd>toxic metal removal</kwd><kwd>water purification</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Allan G.G., Altman L.C., et al.
