The burner has a combustion chamber(12) and a flame tube(18) with perforations(24) in its side wall corresponding to a defined pattern. The pattern of perforations consists of holes of different sizes selected so that determined frequencies of oscillation of the flame tube through interferences ...
Figure 1. Effect of sonication time on the ultrasound-assisted digestion efficiency. The effect of digestion temperature was then evaluated from 30°C to 80°C. The results shown in Figure 2 indicate that the UAD efficiency increased with temperature from 30°C to 50°C, and then reached equi...
