3.3. Effect of temperature
Temperature is one of the main factors affecting the separation of
phases in cloud point extraction. Thus, a study was conducted to select
the range of temperatures that promote higher analytical signals for
manganese. The range of temperature studied was 25 °C to 70 °C.
According to Fig. 6, the highest analytical signals were obtained when
the temperature varied in the range of 55 °C to 70 °C. The temperature
of 60 °C was thus chosen for the next experiments
