文摘

Iowaites with designed Mg/Fe ratios were synthesized for treating As-bearing waters. Increase in the Fe/Mg ratio of iowaite enhances its As uptake capacity. Anion exchange is the primary mechanism for water dearsenication by iowaite Iowaite is an anion clay promising for treatment of As-contaminated waters.
