Abstract
Sodium lignosulfonate (SLS) is one of natural surfactant that can be modified from lignin. The utilization of natural surfactant of SLS is widely studied by researchers. This paper will study the synthesis of a natural surfactant of SLS from rice husk lignin by ultrasound assisted – sulfonation and the characteristics of SLS based on FTIR spectra. The reaction was carried out at the temperature of 60 °C and the time of 30 minutes. From the experiment can be concluded that sulfonation process with ultrasonic irradiation has advantages compared with conventional heating, i.e. lower temperature, shorter time and higher yield.
