| dc.description.abstract | Wool and h a i r c o n s t i t u t e a major component of e f f l u e n t materials in the tanning industry. Since they are insoluble in aqueous medium where most of the tanning processes are undertaken, it becomes necessary to i n v e s t i g a t e other sources that will convert their i n s o l u b i l i t y into a useful process and cut down the cost of production Conditioned native and modified Yankasa wool f i b r e s were treated with metal ions and the uptake was measured. The e f f e ct of metal ion uptake on the mechanical properties of the wool was a l s o determined. Yankasa wool f i b r e s impregnated with m e t a l ions were subjected to infrared spectroscopic s t u d i e s . These s t u d i e s showed that interaction between the reactive groups in wool (hydroxyl, amino,phenolic and carboxyl groups etc) and the electron d i f i c i e n t metal ions r e s u lt in complex formation. As a r e s u l t , Yankasa wool f i b r e s which h i t h e r t o are drained i n t o effluent tanks and l a t e r c o l l e c t e d and burnt, can now serve as scavengers for r e t r i v i n g expensive and toxic metal ions from i n d u s t r i a l water. Furthermore, the treatment has been found to improve the t e n s i l e strength, f l e x i b i l i t y and modulus. | en_US |
