One of the household methods most used to prepare the coffee beverage is the coffee
dripping method, which generates millions of tons of coffee waste (CW). Its disposition …

In this work, we develop chitosan/xylan-coated magnetite (CsXM) nanoparticles as eco-
friendly efficient adsorbents for the facile removal of contaminants from water …

The growing consumption of anxiolytic drugs like diazepam (DZP) has aggravated the
problem of persistent organic pollutants in water. Due to its characteristics, the removal of …

Spent coffee grounds are recognized as a green and sustainable resource of cellulose
