removal of metals from acidic ,wastewater, by adsorption was investigated. ,Acid, extraction (Type A) and alkaline extraction (Type B) gelatin hydrogels were cross-linked by glutaraldehyde. This gave sufficient cross-linking to both types of gelatin hydrogels. Copper recovery test revealed that the cross-linked

The 11003 alkalinity present in the ,wastewater,, however, may be used for ,neutralizing acid, (,equation, 10). HCO3*H - > - 11 2 0+C0 2 (10) If chlorine is used in a two-step breakpoint system at a dosage not to exceed that for the formation of nonchioramine (5:1 C1 2 :NH 3 -1J) in the first stage, and ,acid, formed during the ,reaction, produces CO 2 at a lower pH such as 6.

The Overallprocess ,reaction, of metalacid ,wastewater, - neutralization process by limestone can be written as follows: CaCO. 3 ++ 2H = Ca. 2+ + H. 2. O + CO. 2 (5) ,Equation, represents the condition where dissolution of 5 calcite produces "alkalinity" in excess of "acidity" production and raises the pH above 6.4. The implication of ,reaction, (6)

The same ,equation, relating the concentrations of ,acid, and base applies. The concept of neutralization is not limited to reactions in solution. For example, the ,reaction, of limestone with ,acid, such as sulfuric ,acid, is also a neutralization ,reaction,. [Ca,Mg]CO3(s) + H2SO4(aq) → (Ca2+, Mg2+)(aq) + SO42−(aq) + …
