Abstract:The ultrafine high-purity ferrous oxalate was prepared from ferrous sulphate and oxalic acid using dispersion agents.The effect of the factors on particle size was investigated,and the optimal conditions were obtained as follow:dispersion agent concentration 20%~25%(m/m),reaction temperature 30℃,ferrous sulphate concentration 220 g/L,feeding time 20~30 min. Under the optimum conditions,the particle size and purity of the product was less than 3.0 μm and 99.5%,respectively.
Key words:ferrous oxalate;ferrous sulphate;oxalic acid; ultrafine;high purity
