DOI: 10.1007/s11356-022-19366-w
Abstract: Mechanisms of Cr(VI) reduction by Fe(II) modified zeolite (clinoptilolite/mordenite) and vermiculite were evaluated. Adsorbents were treated with Fe(SO4)ยท7H2O to saturate their exchange sites with Fe(II). However, this treatment decreased their CEC and pHPZC, probably due… read more here.

DOI: 10.1016/j.jece.2019.103107
Abstract: Abstract A novel low-cost adsorbent was produced from clay mineral of vermiculite using chemical modification. The vermiculite was modified with polyamide through in-situ interfacial polymerization. Adsorption performance of the modified adsorbent was investigated for methylene… read more here.
