Adsorption of copper (II) ions from aqueous solutions using waste materials

Razvoj industrije, porast stanovništva i urbanih sredina doveli su do stvaranja velikih količina otpadnih voda. Onečišćenje rijeka, jezera i mora dovelo je do uništavanja biološkog fonda i opasnosti za zdravlje ljudi i životinja. Higijenski ispravna voda jedan je od osnovnih preduvjeta dobrog zdravlja. Razvojem svijesti o važnosti vode, ljudi su u potrazi za najisplativijim i najekonomičnijim metodama za njeno pročišćavanje. U ovom završnom radu poseban naglasak stavljen je na adsorpciju kao izuzetno učinkovitu metodu u pročišćavanju voda i to za smanjenje koncentracije teških metala u otpadnoj vodi.Bakar kao teški metal često se u povišenim koncentracijama pronalazi u vodi, stoga je cilj ovog rada usmjeren na adsorpciju bakar(II) iona iz vodenih otopina pomoću otpadnih materijala.Development of industry, growth of population and urban areas have led to the creation of large amounts of wastewater. Pollution of rivers, lakes and the sea has led to the destruction of the biological fund and dangers to human and animal health. Hygienically correct water is one of the basic prerequisites for good health. By developing an awareness of the importance of water, people are looking for the most cost-effective and economical methods for its purification. In this final paper, special emphasis is placed on adsorption as a highly efficient method for water purification, especially for reducing the concentration of heavy metals in wastewater.Since copper is a heavy metal that is often found in elevated concentrations in water, the aim of this work was to focus on the adsorption of copper (II) ions from aqueous solutions using waste materials
