【Abstract】 The choice of wavelength in on-line measurement of pulp Kappa number is deeply affected by electropositive units during batch pulping. It is studied to use optical analysis method, including choosing the range of wavelength and validating its rationality, which supply the theory basis for the application of technique in on-line measurement of acidic magnesium sulfite pulp Kappa number.更多还原
