Research carried out by the
Department of Chemical Engineering, University
of Granada, makes it possible to remove chrome,
a hard metal that can be dangerous for humans.
The process is based on biosorption, which is
a property of certain types of biomass to retain
pollutants, reports www.medindia.net.
It can be used to purify water from painting,
tannery or the galvanising industry, among others.
A question that invariably arises whenever
olive oil is obtained is what we can do with
its agricultural residues, such as olive vegetable
water, browse leaves, or solid waste known as
‘alperujo’? The study,
carried out by Germán Tenorio Rivas,
has found an interesting use for the apparently
useless olive stones: they eliminate hard metals
– chrome, to be precise – by biosorption
in sewage water from paint, tannery or galvanising
industries.
