Abstract

The effect of TRANSITION METAL IONS on optical properties of hydrogen peroxide bleached CHEMOMECHANICAL PULP of a mixture of northern Iran hardwoods was studied. Hand sheets were made using deionized water, TAP WATER and water containing Al+3, Cu+2, Mn+2, Fe+3, Fe+2 ions. Also, the effect of DIPA Spray on minimizing the impact of these metal ions in the processing water on brightness as well as its stability both before and after accelerated photo aging was investigated. The results indicated that brightness loss due to metal ions is as high as 4-5 points. It was also shown that using DTPA in small amounts could recover the brightness that was lost due to the presence of TRANSITION METAL IONS.
