Increasing arsenic immobilization capacity of a binder prepared by arsenic-containing biohydrometallurgy waste: Effects of ferric/ferrous salts addition

The aim of this study was to improve the immobilization capacity of a binder prepared from As-containing biohydrometallurgy waste (BAW) on arsenic (As) by modifying it with ferric/ferrous salts. The study investigated the chemical fractions of As and its leaching characteristics. Results indicated that the addition of ferric/ferrous salts...
