We were interested in this work by the modification of hydrolyzed poly (acrylamide) which allow us to obtain a new copolymer based on acrylamide and p- phenylenediamine (PPD). The properties of the obtained copolymer and its structure and composition were established by H-1 NMR, FTIR spectroscopy's and by TGA analysis. The prepared copolymer was used as a flocculent substance in the aim to remove turbidity from wastewater. Several experimental parameters such as pH of water, initial turbidity, flocculent concentration and dyes concentration, and their effects on the flocculation process were studied. The considered results show that the studied copolymer is good flocculent and efficient at a very low optimum concentration.
