  author={Abd El-Shafey Ibrahim Ahmed},
Acrylic acid was crosslinked with N,N′-methylenebisacrylamide followed by a reaction with hexamethylenetetramine (HMTA) to form a new hydrogel, Gel (2). Water absorbance rate and retention of Gel (2) were characterized. At the same time, factors affecting absorbance rate such as pH, temperature, and ions concentration were studied. The rate decreased with decreasing pH and increasing ions concentration, whereas increased with raising temperature. The effect of the hydrogel on bacterial… CONTINUE READING
