Low cost adsorbents for the removal of organic pollutants

2012-12-30  Blast furnace slag. Steel plants produce a large volume of granular blast furnace slag as a byproduct, which cause disposal problem. It is being used as filler or in the production of slag cement. It has been converted into an effective and economical adsorbent for the removal of some toxic organic pollutants from the water as well as wastewater.

Synthesis of highly effective absorbents with waste

2017-3-1  Water quenching blast furnace slag (WQBFS) is widely produced in the blast furnace iron making process. It is mainly composed of CaO, MgO, Al 2 O 3, and SiO 2 with low contents of other metal elements such as Fe, Mn, Ti, K and Na. In this study, WQBFS was treated with grinding, hydrochloric acid acidification, filtration, filtrate extraction by alkali liquor and a hydration reaction.

Kinetics of the reaction of iron blast furance slag

2004-3-1  Sorbents highly reactive towards SO 2 have been prepared from iron blast furnace slag and hydrated lime under different hydration conditions. The reaction of the dry sorbents with SO 2 has been studied under the conditions similar to those in the bag filters in the spray-drying flue gas desulfurization system. The reaction was well described by a modified surface coverage model which assumes

Preparation of a new sorbent with hydrated lime and blast

2009-7-30  The removal of dissolvable inorganic phosphate (H 2 PO 4 −) by sorbents prepared from hydrated lime (HL) and blast furnace slag (BFS) was fundamentally studied by an orthogonal experiment design.Based on statistic analysis, it is revealed that the weight ratio of BFS/HL is the most significant variable, and an optimized preparation condition is figured out.
