sunflower waste biomass as an remarkable adsorbent for removal heavy metals from aqueous solution

background: today, through various industrial processes, toxic heavy metals are released into aquatic environments that are harmful to the ecosystem. in the present investigation, removal of such contaminants from industrial wastewater is necessary. the purpose was made to extend an ecofriendly technology by using a bio carbon generated from sunflower waste biomass. methods: the impact of initi...

Removal of perilous dyes from aqueous solutions with CuO adsorbent

Nanocrystalline Akaganeite as Adsorbent for Surfactant Removal from Aqueous Solutions

The present study presents the effective use of nanocrystalline akaganeite for the adsorption of an anionic (SDS), a cationic (CTAB), and a nonionic (tween80) surfactant from wastewater. Equilibrium experiments, as well as thermodynamic analysis, were performed. The maximum SDS adsorption occurs at the lowest pH value (5), the opposite is observed for CTAB (pH = 11), while for tween80, the chan...

Using Generation 3 Polyamidoamine Dendrimer as Adsorbent for the Removal of Pentavalent Arsenic from Aqueous Solutions

Introduction: Arsenic is known as a carcinogenic compound in drinking water. It can cause acute and chronic effects on human health. In this study, the effect of polyamidoamine dendrimer generation 3 (PAMAM G3) as adsorbents for removal of arsenic (V) from aqueous solutions was evaluated. Materials and Methods: Adsorption experiment was studied in batch system and the effect of different varia...

Natural Zeolites Application as Sustainable Adsorbent for Heavy Metals Removal from Drinking Water

Background: There are great resources of natural zeolite in Iran. Zeolite, an inorganic ion-exchanger, may be used as a suitable technical-economical solution for water treatment in many regions of Iran. In this study, the characterization of natural zeolite natrolite and the feasibility of removing hardness, cations, and anions were investigated. Methods: First, zeolite composition and type...
