Reaction: AcidRain's Imagine Cup Achievement 项目 2008/07/09 It appears that Team AcidRain's achievement at the 2008 Imagine Cup Finals in Paris has caught the imagination. The team, which hails from NUI Maynooth, has created a means of enabling diesel engines to use vegetable oil. They ...
Even though the above-mentioned scholars have made a lot of contributions to the simulated acid rain tests and the chemical–mechanical models for geological materials. There are few studies on the strength tests of loess samples and their mechanical model considering the internal chemical reaction of...
Aluminum compounds are treated under anhydrous conditions to prevent violent reactions, recover solvent, and form Al compounds suitable for landfill by reaction with anhydrous hydrolysis agent, eg calcium hydroxide. /Aluminum compounds/SRP: The most favorable course of action is to use an alternative ...
The synthetic acid rain solution (SAR) was prepared using the following compounds: Na2SO4(0.2 g/l) (Zorka Pharmacy, Serbia), NaHCO3(0.2 g/l) (Zorka Pharmacy, Serbia) and NaNO3(0.2 g/l) (Zorka Pharmacy, Serbia)66. A pH value of 2.42 for the synthetic acid rain was achi...
Acid rain in the pollution sense is produced by the conversion of the primary pollutants sulfur dioxide (SO2) and nitrogen oxides (NO and NO2) to sulfuric acid (H2SO4) and nitric acid (HNO3), respectively, to generate an acid solution with a pH lower than 5. In fact, the term acid ...
The corrected right-angle hyperbolic model proposed by Ye (2007) (Equation (1)) was used for curve fitting of the optical response [29]. The maximum Pn (Pmax), light saturation point (LSP), light compensation point (LCP), apparent quantum efficiency (AQY), and dark respiration rate (Rd...
Acid rain is the primary cause of soil acidification in the soils of highly industrialised regions [21]. Rainwater becomes acidic because of the dissolution of atmospheric carbon dioxide (CO2), which undergoes a reaction as presented in chemical Equations (1)–(3). ...
These aerosols can then reform into sulfur dioxide (SO2), a constituent of acid rain, though volcanic activity is a relatively minor contributor to acid rainfall. More From Britannica oxyacid: Sulfuric acid Sulfuric acid is a very strong acid; in aqueous solutions it ionizes completely to ...
Therefore, an alternative approach to obtain high molecular weight polylactic acid is through azeotropic dehydration. This method efficiently removes water from the reaction medium, by using an organic solvent, forming an azeotrope with water without the need of chain extenders or adjuvants (Li et al...
The general form of the ionisation reaction is: HA ⇌ H+ + A⁻ The concentration ratio for both sides is constant given fixed analytical conditions and is referred to as the acid dissociation constant (Ka). Ka is defined by the following equation: \[Ka=[H^{+}][A^{-}][HA]\] ...
