Silica gel (SiO 2) is an adsorbent made from the ,neutralization, of sodium silicate with mineral ,acid, 47. The surface area of silica gel ranges from 300 to 700 m 2 /g 51, 52. Although it is commonly used as a desiccant 53-55 and an adsorbent to separate organic compounds from one another, it is not commonly used in water or ,wastewater, treatment.

In general, ,neutralization, followed by sedimentation is used for the treatment of electroplating ,wastewater, because of low treatment cost and high stability of treated water quality. However, this method results in the production of large amounts of heavy metal sludge that cause secondary pollution and additional cost.
