Laboratory-prepared iron oxide coatings on sands

Prior to iron oxide coating, the substrate silica sand was wet-sieved over the #200 sieve (75 μm) to remove all fines, and then digested in H 2 O 2 (3% solution) to remove surface traces of organic matter. Iron oxide coatings onto sand were accomplished by co-adsorption between the iron oxide and quartz.
