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.
- Mass Transfer in Porous Solids
- Adsorption of Heavy Metals on Natural Clays and Zeolites
- Removal of Pharmaceuticals from Aqueous Solutions by Adsorption on Novel Carbon Materials
- Cation Exchange of Heavy Metals and Ammonia on Natiural Clays and Zeolites
- Biosorption of Heavy Metals on Natural and Chemically Modified Waste Biomaterials
- Degradation of Toxic Organic Compounds by Avanced Oxidation Processes
