    摘要: The present invention provides a non-destructive method for measurement of recycled pulp or pulp immersed in suspension. The method of the invention enables real-time or on-line evaluation of particles in recycled pulp or pulp, especially for evaluation of particles including inks contained in recycled or deinked pulp for their characteristics including sizes, shapes, areas, amount, concentration, absorption coefficients, spectral characteristics such as color locus (L*, a*, b* values) and parameters, which are equivalent to the effective residual ink content (ERIC) or the ink elimination (IE) or detachment (ID), but independent of the size distribution of inks. The method can additionally be used for real-time or on-line recognizing inks from the other particles and distinguishing inks, which are already detached from or still attached to fibers. The method can further be used for real-time or on-line identification of the pulp fibers and fiber-based particles in recycled pulp or pulp from the non-fiber particles.
