dc.description.resumo	This paper describes nickel ferrite (NiFe2O4) synthesis by sol-gel modified by Ionic Coordination Reaction (ICR) cross-linked technique according to nitrate concentration on organic based solution, aiming a reduction in losses associated to production process. Chitosan is used to increase the coordination between the ions along with chelate agent glutaraldehyde, used to form the gel in sol-gel technique. Calcination process was also applied, with temperature of 1100 C, 10 C/min step for 10 h, to eliminate organic composes and obtain NiFe2O4 with particles over 300 nm diameter. The obtained efficiency results show that A03 (120 g/L) sample has better final efficiency between the proposed concentrations, reaching a 57.39% value with 95.86% purity, estimated by XRD and EDS. SEM was also performed, and confirmed size distribution based on XRD results, presenting homogeneous morphology along with narrow particle size distribution	pt_BR
