title: Stabilization/solidification of waste ferrous sulphate from titanium dioxide production by fluidized bed combustion product.
abstract: A treatment procedure to allow the disposal of waste ferrous sulphate was developed. This waste contains sulphuric acid and originates from titanium dioxide production. The process is based on simultaneous neutralization and stabilization/solidification (S/S) of the waste by means of fluidized bed combustion product (FBC-P). The prepared stabilized waste specimens have a solid matrix and their batch leachates display practically neutral pH and also satisfactory conductivity values. The leachate composition is notable in its absence of toxic metals and even iron.
