a) Air Quality in the City of San Luis Potosi
A multidisciplinary group led by Dr. Leyva Ramos conducted the most comprehensive study of air quality in the city of SLP. It was evaluated the air quality in an urban area of the city of SLP. The results revealed that the suspended dust particles contained various metals and arsenic, and were very toxic.
b) Removal of Fluoride and Arsenic from Water
In several states, water having arsenic and fluoride levels above the limits is consumed, representing a health problem. Pristine bone char and modified with iron nanoparticles is an excellent adsorbent to remove fluoride and arsenic from drinking water.
c) Adsorption of Pharmaceuticals from Water
The presence of pharmaceuticals in water resources represents a risk to human health because they are toxic. The pharmaceuticals can be removed by adsorption on activated carbons (CA), mesoporous CA, AC fibers, and other carbon nanomaterials.
d) Removal of Heavy Metals from Industrial Wastewater
The adsorption on natural clays and zeolites can be successfully applied for removing toxic metals from water.
e) Use of Agroindustrial Waste
The biosorption of heavy metals on agricultural and forestry wastes (wood sawdust) has been studied as possible alternative for commercial use.
f) Photodegradation of Pharmaceuticals in Water
Advanced oxidation processes have been applied to the degradation of organic compounds in water.
