Here we document multiple, independent analyses and show evidence that bacterial sulfate reduction, metal attenuation, and thus, partial natural acid mine remediation, can occur in the moderately acidic, pH 4 environment.
A pot experiment, in which wheat was grown for 35 days in a moderately acidic soil of low P status and a calcareous soil of moderate P status, was conducted.
Tempranillo, moderately acidic and fresh-smelling, accounts for between 70 and 90percentt of almost every fine Rioja red wine.
Results indicate that pavements altered soil pH from moderately acidic (pH = 5.75) to more neutral levels (pH = 6.3).
The soil was moderately acidic (pH = 5.7) and low in organic carbon content (8.7 g kg−1).
Nickel immobilized on a moderately acidic support and palladium on activated carbon catalysts has shown better yields of kerosene, under mild conditions.
The methanol-to-hydrocarbons (MTH) reaction was studied over a moderately acidic zeotype material, H-SAPO-5, at 350 450 °C and with WHSV = 0.3 5 h−1.
The high surface area, moderately acidic meso- and macro-porous support was prepared with the mixing of alumina and ultra-stable Y zeolite (US-Y).
These sites involve moderately acidic hydroxyls, less acidic than Al associated bridged hydroxyls but significantly more acidic than hydroxyls which terminate the crystal at the outer surface.
A first reduction step that should be attributed to superoxide ions was observed in moderately acidic and in moderately basic media.
Physicochemical characterisation and catalytic properties of a new hydrothermally stable mesoporous mesophase titanium-silicate, denoted as Ti-MMM-2, synthesised under moderately acidic conditions are reported.
