Soybean oil (SBO) was miscella bleached in hexane using carbonized hulls of Jojoba (Jo), Jatrova (Ja), Peanuts (PN) and Pistachios (P) as alternatives to bleaching clays. Evaluation of bleached crude ...
The global decline of reef-building corals is due in part to the loss of algal symbionts, or ‘‘bleaching,’’ during the increasingly frequent periods of high seawater temperatures [1, 2]. During ble...
We report a comparative experimental study of the attenuation spectra transformations for a series of Yb doped alumino-germano silicate fibers with different contents of Yb3+ dopants, which arise as t...
The peroxymonocarbonate mono-anion (HCO4─) is generated in solutions containing bicarbonate anions (HCO3─) and hydrogen peroxide (H2O2). The mono-anion is believed to have a pKa value of ca. 10 and as...
The peroxymonocarbonate mono-anion (HCO4─) is generated when the bicarbonate anion is added to a H2O2 solution. The mono-anion is believed to have a pKa value of ca. 10 and as such would start dissoci...
By removing the primary fines from an oxygen-delignified mill birch pulp, a fiber fraction was obtained having low metals content and no extractives. After DEDeD bleaching the fiber fraction had somew...
The objective of this study was to utilise desizing liquors of starch-sized fabrics using glucoseoxidaseenzymes for bleach to produce hydrogen peroxide from glucose units of the starch removed; glucos...
The present study seeks to investigate the bleaching of palm oil with activated plantain peel ash (APPA). Concentrations of β-carotene, iron, copper, lead, and phosphorus in the crude (unbleached) and...
In order to determine the effect of bleaching conditions on the physical and optical properties of pulps during the bleaching of CTMP with H2O2, 48 bleaching trials were carried out. After the analys...
In this research, sodium hydroxide + hydrogen peroxide, sodium hydroxide + calcium hydroxide + hydrogen peroxide, hypochlorite and hydrochloric acid were applied to pine (Pinus sylvestris L), oriental...
The objective of this research was to determine the effects of sodium hydroxide + hydrogen peroxide, sodium hydroxide + calcium hydroxide + hydrogen peroxide, hypochlorite and hydrochloric acid applie...
The objective of this research was to determine colour changing proporties of sodium hydroxide + hydrogen peroxide, sodium hydroxide + calcium hydroxide + hydrogen peroxide, hypochlorite and hydrochlo...
The aim of this research was to determine the effects of bleaching chemicals on the bending strength of wood. For this purpose, sodium hydroxide + hydrogen peroxide, sodium hydroxide + calcium hydrox...
This study was performed to determine the effects of bleaching and impregnation processes on the hardness of the varnish layer in beech wood. For this purpose, samples were impregnated with Tanalith-C...
The physical, chemical, and morphological characteristics of Acacia auriculiformis were evaluated in terms of its suitability for papermaking. The fiber length (1.1 mm) of A. auriculiformis in this st...
