摘要：

Chromium Cr(VI) is highly toxic, carcinogenic, mutagenic to most of the living organisms when its concentration level is higher than 0.05 ppm, and extremely mobile than Cr(III). Therefore, there is a great importance to remove Cr(VI) from aqueous solution, to prevent the deleterious impact of the Cr(VI) on the human health. The composite nanofibers had a positive effect on the absorption of Cr(VI) ions under neutral and acidic conditions. The saturated adsorption reached the highest when pH was 2 at(76.98%), whereas it was in low level when pH was 9 (59.13%), that was in composite nanofibers containing the same chemical components when CNTs (1g). This paper propose a method that aims to remove Cr(VI) from wastewaterof the textile dyeing industryusingcompositenanofibers solution.
