Optimization of the process of obtaining an ion exchanger based on a carbamide-phenol-formaldehyde oligomer

Abstract

To obtain an ion exchange compound for process water treatment, a relatively environmentally friendly oligomer was sulfonated by adding a sulfogroup to the benzenering in the oligomer. The dynamic change capacity of the obtained ion exchanger was 0.74–0.98 mg-eq/g, the static change capacity was 1.25–3.22 mg-eq/g, the volume density was in the range of 1189–1206 kg/m3. The study of the optimal parameters of the process of obtaining an ion exchanger (sulfocationite) based on a carbamide-phenol-formaldehyde oligomer was carried out by planning a multifactorial experiment. The optimal value of the output parameter is 78,13 %.
