Mg(OH)2H2O2 bleachingA partial substitution of NaOH by Mg(OH)2 as alkali source of oxygen delignification of OQP bleaching of wheat straw NaOH-AQ pulp was carried out in this paper. The effects of substitution of Mg(OH)2 for NaOH on pulp properties and delignification characteristics ...
被引量: 2 摘要: Preparing magnesium hydroxide-nanoparticles comprises: dissolving a magnesium-precursor in a polyol to form a solution (a); preparing an aqueous solution (b) of an alkali-metal hydroxide and a polyol, or quaternary ammonium hydroxide (1) and the polyol or metal alcoholate ...
In order to reduce the cost of the production, Mg-based waste materials can be used in preparing MgH2 [269,270], RHCs based on magnesium such as Mg(NH2)2-LiH [271], and alkali borohydrides [272]. Pistidda et al. [269] and Hardian et al. [275] explored the conversion process ...

(NH 4 ) 2 SO 4 –ZnSO 4 –H 2 O, and (NH 4 ) 2 SO 4 –CuSO 4 –H 2 O have been used to determine the ternary interaction parameters in the Pitzer model and to calculate the solubilities and deliquescence humidities of the Tutton salts (NH 4 ) 2 M II SO 4 ·6H 2 O ...
Moreover, most previous research has been performed in strong acid or alkali media aiming at hydrogen fuel cell applications, while neutral media that are widely used in Mg-air batteries acquired little attention. 3.2. Air cathodes for Mg-air batteries In general, the air cathode of primary Mg...
Hydrolysis of borohydrides [15,16], metals [17,18], alcohol-alkali [19,20], and metal hydrides [21,22] is promising for hydrogen production. In the above-mentioned materials, Mg-based materials have high hydrogen storage capacity (7.6 wt%) and are abundantly available on Earth [23]. ...
