Adsorption of gold on activated carbon from gold bromide solutions was examined as a function of pH, particle size, amount of carbon, initial gold bromide concentration, bromine concentration, temperature, and various cations and anions. The pH did not have any effect on gold adsorption below pH 6. Above pH 6, pH had a dramatically negative effect.

BACKGROUND A normal heart rate reflects the balance between the sympathetic and parasympathetic autonomic nervous system. When the difference between heart rate at the end of an exercise test and after 1 min of recovery, known as the 1-min heart rate recovery, is 12 beatsmin, this may indicate an abnormal delay. We sought to compare physical activity patterns and subjects functional ...

A green method, using pulsed spark discharge PSD to synthesize colloidal gold, is studied in this thesis. PSD uses spark discharge to synthesize gold nanoparticles AuNPs in deionized water DIW andor ethanol EtOH. While gold nanoparticles have widespread applications in many fields, especially for the human body, in use them must overcome the influence of NaCl and pH value therefore ...

For example, consider a mine with a gold head grade of 2.2 gt that has been evaluated to have a recovery of 94 per cent at the 2.2 gt head grade. If the 94 per cent recovery value is used to determine a break-even grade, it would be 0.4 gt, which implies a tails grade of 0.02 gt.
