https://doi.org/10.22090/jwent.2020.04.003

Abstract
  In this study, thiol-functionalized nanostructure silica type MCM-41 was successfully prepared via the facile one-pot hydrothermal method with low amounts of the directing agent. The mesoporous silica indicated a remarkable adsorption behavior toward Pb(II) ions without any interference of the competing ...  Read More

Volume 5, Issue 4 , October 2020, , Pages 358-368

https://doi.org/10.22090/jwent.2020.04.006

Abstract
  Homogenous catalysis which the catalyst operates in the same phase as the reactants is definitely efficient in catalysis processes while it suffers from the impossibility or inconvenience of the removal of the catalyst from the reaction media. In this research, In2S3 nanoparticles were synthesized by ...  Read More

Investigation and Comparison of Fluoride Adsorption Behavior on a Hybrid Material Containing Zirconium Dioxide Coated on γ-Alumina (60 and 90) and Their Initial Precursor in Aqueous Solution

Volume 3, Issue 3 , July 2018, , Pages 265-272

https://doi.org/10.22090/jwent.2018.03.007

Abstract
  In the current work, the natural zeolite was modified with cobalt hexacyanoferrate and employed for adsorbent of Pb(II) ions from aqueous solution. The modification was approved by XRD and FTIR techniques. The Pb(II) adsorption capacity enhanced by 1.8 times from 60 mg/g (natural zeolite) to 100 mg/g ...  Read More
