Water pollution is the contamination of water bodies such
as lakes, rivers, oceans, and groundwater caused by human
activities, which can be harmful to organisms and plants which
live in these water bodies. Water pollution by toxic heavy metals
through the discharge of industrial waste is a worldwide
environmental problem. Since copper is a widely used material,
there are many actual or potential sources of copper pollution.
Although a limit of 2 mg/L was proposed by the World Health
Organization as the provisional guideline value for copper content
of drinking water, intake of excessively large doses of copper by
man leads to severe mucosal irritation and corrosion, widespread
capillary damage, hepatic and renal damage and central nervous
system irritation followed by depression. Severe gastrointestinal
irritation and possible necrotic changes in the liver and kidney
could occur.
This study evaluates the use of silica fume waste material
in the remediation of polluted heavy metal water to remove copper
ions. For studying metal adsorption, 1 g of silica fume has been
taken as adsorbent and then it has been suspended in 50 mL of
1 mg/mL CuCl , at pH between 3 and 11 with / without
2
apocarbonic anhydrase and contacted batchwise in a thermostatic
(t = 30 °C±0.1 °C) water-bath agitator for 1 h to enable
equilibration of the sorbent and solution phases. The copper
concentrations in the samples taken from the silica fume treated
aqueous solutions of polluted river water and CuCl solution
2
with/without apocarbonic anhydrase have been determined by
spectrophotometric method using 1-amino-2-hydroxy-4-
-naphthalenesulfonic acid. The experimental investigation results
show that activated silica fume has a high level of adsorption
capacity for Cu2+ ion. Consequently, it is concluded that the silica
fume can be successfully used for the removal of the copper ions
from the aqueous solutions with heavy metals.

The European chemical industry is the world’s top exporter
and importer of chemicals with a record of €47 billion trade
surplus in 2010 [1] .The links between the chemical industry and the
water sector are multiple. The chemical sector is both, a main
water consumer, it uses the 11% of the water abstracted in the
continent and at the same time it is the provider of a great
number of products employed in the treatment of drinking and
waste water.
The European Commission (EC, 2007a) [2] recognized that
water scarcity and droughts will constitute a major challenge for
the European Union in the near future. At least 11% of the
European population and 17% of its territory have been affected
by water scarcity to date. Recent trends show a significant
extension of water scarcity across Europe threatening to increase
the € 100 billion costs and losses associated to these phenomena
over the past thirty years. Furthermore, the gaining importance of
upcoming industrial sectors such as white biotechnology is
expected to result in higher demands for water adding on the
current one. In view of this, it is clear that water sustainability is
a main challenge to confront in the near future.
ChemWater is an FP7 project (NMP-2010-CSA-4-266851)
that intends to coordinate European strategies on sustainable
materials, processes and emerging technologies. It focuses on
chemical and water sectors trying to establish synergies in the
future development of both and to promote a shift in the paradigm
of water from its current status of interminable commodity to a
valuable raw material, what will result in an optimized industrial
water management. The project looks at the European chemical
industry as a provider of solutions for the whole water
management cycle. Therefore this project fosters a new point of
view: that of “chemistry for water” alongside the more traditional
“water for chemistry”.
The project brings together the WssTP and SusChem
Technology Platforms as well as the networks of excellence EMH,
ENMIX and ERIC. Experts from the two sectors as well as
relevant professionals and stakeholders will jointly define a
common long term vision that will enable a sustainable industrial
water management in Europe. From that reference point, the
consortium will detect the technological, legislative and social
gaps to fill with research initiatives in order to achieve
the 2050 Vision for ecoefficient water management.
