Abstract: Effects of surfactants in flotation deinking operation of ONP has been studied using 5 surfactants namely Triton x-100, Tween 80, Brij-35, Anmol surfactant DI and Oleic acid. It is observed that Tritron x-100, Brij-35 and Oleic acid have optimum dosage after which the deinkability factor and flotation rate constant starts decreasin with increasing dosage. In case of Tween 80 and Anmol DI with the increase in their dosage, the deinkability factor and flotation rate constant goes on increasing resulting in better quality pulp while the loss of fines and fibres also increases. It appears that Tween 80 and Anmol DI also accumulate dust or fines along with the ink to form the medium size agglomerate which can be carried away with the air bubble as foam with the increase in dosage. The ink agglomerate size increases with the increase in dosage of Triton X-100, Brij-35 and Oleic acid resulting in its reversal back to the pulp beyond optimum dosage.
