Abstract
Fosfor(P) je kemijski element, jedan od glavnih hranjivih tvari za rast biljaka, kako kopnenih tako i vodenih te je široko rasprostranjen u prirodi. U vodenim sustavima javlja isključivo u obliku fosfata te je često jedini ili jedan od ograničavajućih faktora za rast biljaka vodenog okoliša. Dakle, ako se unos P povećava, povećava se proizvodnja biomase vodenih biljaka. Prekomjerna proizvodnja biomase vodenih biljaka može uzrokovati estetske probleme povezane s njihovom fizičkom prisutnošću u vodnom tijelu i neugodni okus i miris vode. Prekomjeran unos fosfora u vodno tijelo uzrokuje i proces eutrofikacije, prekomjerne pojave otopljene organske tvari uslijed razgradnje biljnog materijala, smanjenja količine kisika u vodi što može biti štetno za druge vodene organizme. Budući da je nužno osigurati visoku kakvoću vode i zaštititi vodeni svijet, potrebno je osigurati visoku učinkovitost uklanjanja fosfora iz otpadnih voda koje se ispuštaju u okoliš. Zadatak ovoga rada bio je ispitati učinkovitost uklanjanja fosfata iz otpadne vode adsorpcijom primjenom modificirane ljuske sjemenki suncokreta, nusproizvoda prehrambene industrije. Učinkovitost je ispitana u ovisnosti o koncentraciji fosfata u početnoj otopini, vremenu adsorpcije, pH vrijednosti otopine i masi adsorbensa.
Abstract (english)
Phosphorus (P) is a chemical element that is one of the major nutrients for plant growth, both terrestrial and aquatic plant, and is widespread in nature. In aquatic systems phosphorus occurs only in the form of phospates, and is often the, or one of the, limiting nutrients for the plant growth in the aquatic environment. So, if the intake of P increases, the production of aquatic plants biomass increases. Excessive production of aquatic plants biomass can cause aestetic problems related to their physical presence and unpleasant taste and smell of water. Excessive intake of phosphorus in the water body also causes the process of eutrophication, excessive occurance of dissolved organic matter due to decomposition of plant material, the amount of oxygen in the water decreases to a level that may be harmful to other aquatic organisms. Because of that, it is necessary to ensure high water quality and protect the aquatic world, and remove surplus of phospates from water in most efficiency ways. The task of this graduate thesis was to examine the efficiency of phosphate removal from wastewater in adsorption on modified shell of sunflower husk, a by-product of food industry. The efficacy was tested depending on the phosphate concentration in the initial solution, the adsorption time, the pH of the solution and the mass of the adsorbents.
