Tea test
Wipe the electronic microscope image of black tea leaves, magnified by 500 times. Black tea, which is fully melted and oxidized, displays the surface of wrinkles, which may increase the surface area available to accommodate admission.

To test their hypothesis, the authors purchased the commercial tea bags for the leptone and payments, as well as a variety of loose tea and herbal alternatives: black tea, green tea, Fwani white tea, Oolong tea, Ruybus tea and chamomile tea. Tea bags were different types (cotton, cellulose, and nylon). They fermented the tea in the same way that they drink daily tea, wandering in tea for different periods of time (only seconds to 24 hours) in water with high levels of lead, chromium, copper zinc and cadmium. Tea leaves are removed after slope by pouring tea through the cellulose filter in a separate tube. Then the team measured the amount of toxic minerals that remained in the water and the amount of absorbed leaves.
It turns out that the type of tea bag is important. The team found that cellulose tea bags work better in absorbing toxic minerals from water while cotton and nylon tea bags barely absorbed any pollutants at all – and nylon bags also release pollutants of the precise tiles of the boot. The type of tea and grinding level also played a role in absorbing toxic metals, with accurately ground black tea leaves that play the best in that result. This is because when these leaves are treated, they are wrinkled, which open the pores, adding more space. Tea grinding increases the surface area, with greater ability to connect toxic metals.
But the most important factor was the time of slope: the longer the time is slope, the more toxic minerals are absorbed. Depending on their experiments, the authors estimate that the tea fermentation – using a tea bag descending for three to five minutes in the mug – can remove about 15 percent of lead from drinking water, and even water with concentrations of up to 10 parts per million.
