摘要: Carbon nanotubes (CNTs) have become the focus of attention many scientists and companies worldwide. CNT-based filters a prospective advantage in comparison to commercial already operation because they are light weight do not require electricity operate. This investigation handles filtration efficiency manganese iron from aqueous solution using multiwalled carbon (MWCNTs) (Taunit). The effects different parameters such as CNT filter mass, concentration pH on removal these heavy metals determined. From investigations, could reach 71.5% 52% respectively for 50 ppm, suggesting that Taunit is an excellent adsorbent water. There was significant increase at = 3 8 iron. effect oxidation structural MWCNTs characterized by scanning electron microscope (SEM) energy dispersive spectroscopy (EDS) techniques investigate functionalization with oxygen-containing outer diameter distribution. It found functionalized more efficient removing solutions. Oxidized may be promising candidate metal ion industrial wastewater.
