At the University of Sri Lanka, researchers found that water spinach, or kangkong, was able to absorb about seventy percent of the heavy metal chromium in the water. Another study by Indian researchers pointed out that water spinach can be used to absorb other heavy metals from water such as zinc, nickel, cadmium, lead, cobalt, and others.
Hyperaccumulation of heavy metals is the uptake of heavy metals by plants passed a certain threshold of normal uptake. There are 6 main hypotheses for this phenomena, but the most researched one is the defense-hypothesis which states that the hyperaccumulation helps plants to protect themselves from herbivore/pathogen damage.
Heavy metals are typically found in the middle of the periodic table. These heavy metals are often also transition metals.
No
The scientific name of kangkong is Ipomoea aquatica.
"Kangkong" is a Filipino word for a leafy green vegetable commonly known as water spinach in English.
Not easily. The molecular size of heavy metals means the kidneys struggle to excrete them. Most heavy metals are stored in hair, finger nails and other body tissues. Many, such as copper, lead, iron, are toxic if ingested in large amounts.
Yes, kangkong is a dicot leaf. Dicot leaves have a network of veins that branch out from the midrib in a reticulate pattern, which is characteristic of kangkong leaves.
Heavy metals compounds have frequently toxic properties.

Yes, platinum is heavy compared to other metals.
No, calcium gluconate, magnesium sulfate, and potassium phosphate are not heavy metals. They are inorganic salts commonly used in pharmaceuticals and medicine for various purposes. Heavy metals typically include elements like lead, mercury, and cadmium.
Ammonia is added in heavy metals limit tests to precipitate heavy metals as their insoluble hydroxides. This allows for the separation of heavy metals from other interfering substances in the sample, making it easier to detect and quantitate the heavy metals present.
