Remove As from Energy Drinks

Arsenic is a shiny gray brittle element with both metallic and nonmetallic properties. At present, problems of arsenic contamination and food arsenic poisoning exist in many countries and regions in the world. Simple substance arsenic is nontoxic, while Arsenic compounds are not. Arsenic can enter the body through the digestive tract, respiratory tract, skin mucosa and be absorbed through the lungs, gastrointestinal tract and mucosa, distributed in various tissues and organs of the body along with the blood flow, the highest content is found in skin, hair and fingernails, and part of which is excreted in the urine.

The lethal concentration of arsenic trioxide inhaled by humans is 16mg/m³ (inhaled for 4h), and chronic poisoning may occur if inhaled in small amounts or taken orally for a long time.Symptoms of acute arsenic poisoning include fatigue, vomiting, yellow skin, abdominal pain, headache and neuralgia, and even coma. In severe cases, death results from neurological abnormalities, dyspnea, and heart failure. Fatal poisoning may occur after 5 to 10 minutes of breathing in hydrogen arsenide 1mg/L from the air.

When the arsenic content in drinks is low (10-30mg/ g), it leads to slow growth, reduced pregnancy, more spontaneous abortion, and higher mortality.

Therefore, the removal of arsenic from drinks is crucial. General arsenic removal methods include oxidation, co-precipitation, adsorption, reverse osmosis, etc. Unlike traditional adsorption materials (resin, activated carbon), Si-novation functional silica material has multi-functional groups that can effectively adsorb and remove arsenic, and can be reused.

Si-novation functional silica material has multi-functional groups that can effectively adsorb and remove As from drinks without damaging the flavor.
