    Abstract: It was showed that black citric acid polymer (PN) have capacities to be a potential raw materials for realizing a cationic exchanger seeing that the treated water solution through PN kept a brown color of brown citric acid polymers from PN during its activations with NaOH. So, the objective of this publication was to realize not only materials and ... Show More
