Peroxide bleaching stage. The peroxide bleaching was done after removing transition metal by the complexing treatment (Q-stage). The Q-stage was performed using 0.3% diethylenetriamine penta acetic acid (DTPA) and 1 mol l −1 H 2SO 4 at 65 °C for 60 min to remove transition metals. 35 The metal content in the pulp before and after Q-stage was analyzed by ICP-OES (Optima 3000, PerkinElmer) after hydrolysis with nitric acid in a microwave oven, according to Janzon et al. 36 By heating the water to boiling point, we have decreased the solubility of the dissolved gases. They come out of the solution as bubbles and the remaining water has less gases dissolved, so is less cloudy. H. Berhanu, Z. Kiflie, I. Miranda, A. Louerenco, J. Ferreira, S. Feleke, A. Yimam and H.

Nonpolar molecules, such as those found in grease or oil, do not dissolve in water. We will first examine the process that occurs when an ionic compound, such as table salt (sodium chloride), dissolves in water. At room temperature, the water contains a certain amount of dissolved gases from the air. The water straight from the tap creates cloudy ice cubes because these gases that were dissolved in the water form tiny bubbles in the ice. C. Chen, C. Duan, J.

For PH soda pulps after O-bleaching followed by the mild P 2 stage, a second peroxide bleaching stage P 2 (2% H 2O 2, 1% NaOH) and P 3 (3% H 2O 2, 1.5% NaOH) was performed ( Fig. 3C and 4C). The second P-stage gives an additional brightness increment, reaching 83% ISO for pulp with high PH severity and high peroxide charge in P 3. This holds for both samples from O-stage at 90 °C and 100 °C. However, the viscosity of these samples has been reduced to 400 ml g −1 (O: 90 °C) and 364 ml g −1 (O: 100 °C). Accordingly, samples are at the lower limit of the targeted viscosity range.

So, let's look at solids first.J. R. Kim and K. G.

A huge viscosity increment was already observed for mild and intense soda pulping without prehydrolysis ( Fig. 2D). There is a gradual decrease in viscosity from 870 ml g −1 to 600 ml g −1 and from 440 ml g −1 to 340 ml g −1 with steaming severity for mild and severe pulping. Accordingly, the reduction of xylose content in the PH soda, down to less than 4%, was obtained at the expense of reducing pulp viscosity.

Jon: I've got a question for you guys. Do you think I can fit this length of polystyrene into this jar? H. Harsono, A. S. Putra, R.

Wood Sci., 2016, 62(1), 65–73, DOI: 10.1007/s10086-015-1526-3. The pulps from 100 °C O-stage showed slightly higher bleachability in the subsequent peroxide bleaching, as shown in Fig. 4B. The positive effect of the higher temperature in the O-stage on brightness remains effective after both P stages ( Fig. 4B). The brightness of PH soda pulp after the P 1 stage was better than P 2 stage by 3% and 2.8% for steaming severity of 3.83 and 4.13, respectively. On the other hand, the pulp viscosity was lower by 37 ml g −1 and 53 ml g −1 ( Fig. 3B). However, the negative effect of O-stage on viscosity is equalized in the P-stage, at least for pulps with high PH severity. This indicates that with a high temperature in the O-stage and a high peroxide charge (P 1), good bleaching efficiency can be obtained by simple OQP 1 sequence reaching a brightness of 83.2% and a viscosity of 424 ml g −1 for the PH soda pulp with the severity of 4.13.G.
