Mercerized mesoporous date pit activated carbon—A novel adsorbent to sequester potentially toxic divalent heavy metals from water

Mercerized mesoporous date pit activated carbon—A novel adsorbent to sequester potentially toxic divalent heavy metals from water

A substantive approach converting waste date pits to mercerized mesoporous date pit activated carbon (DPAC) and utilizing it in the removal of Cd(II), Cu(II), Pb(II), and Zn(II) was reported. In general, rapid heavy metals adsorption kinetics for Co range: 25-100 mg/L was observed, accomplishing 77-97% adsorption within 15 min, finally, attaining equilibrium in 360 min. Linear and non-linear is...

Naphthalene Removal From Water by Novel Mesoporous Carbon Nitride Adsorbent

Polycyclic aromatics hydrocarbons are chemical species with two to six fused benzene rings and are well-known toxic hazardous pollutants and highly potent carcinogens that can cause tumors in some organisms.1 In recent years, naphthalene contamination in water systems has drawn increasing attention. Naphthalene originates from natural and anthropogenic sources. Anthropogenic sources include eng...

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...
