Compared with the classic mineral acid
hydrolysis method, solid acid hydrolysis method has mild condition and low corrosion to equipment, and the solid acid can be recycled.
Reaction with the 0.13 M mineral acid
solution at 100[degrees]C and 200[degrees]C temperature under 200 bar pressure resulted in concentrations of approximately 340 ppb and 8500 ppb of the selected "at risk" elements in the final samples taken, respectively.
Lead-bearing brass flakes are removed by magnetic separation; then, mineral acid
leaching removes heavy metal contaminants from the brass fines.
HF is very strong mineral acid
having ability to effectively dissolve insoluble residues in the plants.
Sulphuric acid is strong mineral acid
and its dilution in water is highly exothermic reaction.
plantarum was studied by centrifuging and resuspending cultures in either weak organic acid buffers, such as citric, lactic or tartaric, or in strong mineral acid
solutions, such as hydrochloric or sulfuric solutions.
The range is a PVC-C system designed to handle a wide variety of chemicals, including caustic solutions, inorganic salt solutions, detergents and strong mineral acid
Riman added that he and his team used a biologically produced acid called bio lixiviant, which is expected to be less harmful to the environment than traditionally used mineral acids
which are very acidic.
