This pushes the gold foils off the filter and into the cup. Then, wait for the gold foils to settle to the bottom and get as much water out. After that, you could wait for the water to evaporate out and you are left with just gold. However, the gold foils tend to stick to the cup, so I keep mine in a glass vial with some water.

Sonication is the act of applying sound energy to agitate particles in a sample, for various purposes such as the extraction of multiple compounds from plants, microalgae and seaweeds. Ultrasonic frequencies (>20 kHz) are usually used, leading to the process also being known as ultrasonication or ultra-sonication.. In the laboratory, it is usually applied using an ultrasonic bath or an ...
