摘要：

In this study, the synthesis of nickel oxalate was investigated from an extract solution of nickel laterite using the precipitation method. The experimentation determined the best conditions for nickel oxalate synthesis. Response Surface Method was applied to the experimental data to optimize the process. The kinetics study of the synthesis process shows that the approach using the Avrami model gives a better approach than the firstorder integral model. The activation energy generated from the kinetics study with this model is 36.5221 kJ/mol.
