[China paint information] the emergence of new pollutants in water has prompted the scientific community to study new solutions and alternatives. According to this idea, a team of scientists from the University of Seville recently showed two new ways to check the effectiveness of the experimental data absorption materials that have been done. These two materials can eliminate the organic pollutants in the solution in less than 24 hours

specifically, they have evaluated two types of layered silicates: a highly charged expandable synthetic mica (na-mica-4) and one obtained by cation exchange with organically functionalized mica (c18-mica-4). Layered silicate is a subclass of silicate, including common minerals in very different environments

the results show that c18-mica-4 material can eliminate most pollutants in urban sewage, surface water and drinking water. The study also provided data on the adsorption mechanism and established a significant correlation between the physicochemical properties of the selected standards and the physicochemical properties of emerging pollutants and the adsorption of materials

a total of 18 kinds of organic pollutants were studied, including industrial pollutants, personal care products, anti-inflammatory drugs, antibiotics, antiepileptic drugs, central nervous system stimulants, lipid-lowering agents and other pharmacological active ingredients

among industrial pollutants, several compounds often used as cleaning products and other compounds used as water and oil displacement agents were analyzed. Taking personal care products as an example, two synthetic preservatives methyl p-benzene and propylene p-benzene, which are widely used in cosmetics and drugs, were analyzed. Finally, nine effective pharmacological components (diclofenac, ibuprofen, salicylic acid, trimetazidine, carbamazepine, propranolol, caffeine, chloramphenicol and geferozil) were also detected. Taking different therapeutic effects, these eventually pollute our water, basically, through human excretion

this study studied untreated urban wastewater, treated urban wastewater, surface water from rivers and drinking water

"studies like this and other similar studies have shown the potential of some adsorbent materials in treating different types of polluted water." Estebanalonso, the head of the research project and a professor at the University of Seville, said: "the main goal of this research field is to obtain general materials with high elimination capacity and can be used for a wide range of pollutants."

research in this area will take the following steps: evaluate the role of these materials in eliminating other water pollutants, their application on an industrial scale, and improve the function of the materials themselves
