Abstract
Toksičnost arsena poznata je već desetljećima, a u novije vrijeme dokazana je i njegova kancerogenost. Proveden je velik broj istraživanja koja povezuju povišene koncentracije arsena u vodi za piće i pojave karcinoma kože, pluća i ostalih oblika karcinoma. Stoga se pojavljuje sve veći interes za istraživanjem metoda uklanjanja, odnosno smanjenja koncentracije arsena u vodi, što rezultira poboljšanjem postojećih i uvođenjem novih tehnologija u preradi vode za piće. Cilj ovog diplomskog rada bio je ispitati mogućnost adsorpcije arsena na aktivni ugljen koji je proizveden karbonizacijom ljuske lješnjaka te modificiran zasićenjem s željezovim(III) kloridom. Učinkovitost uklanjanja arsena iz vode promatrana je u ovisnosti o početnoj koncentraciji arsena, vremenu adsorpcije, pH i mase adsorbensa. Ovisnost navedenih parametara praćena je u korelaciji s promjenom temperature te su eksperimenti provedeni u termostatiranoj tresilici. Rezultati istraživanja pokazali su da je postotak uklonjenog arsena proporcionalan s početnim koncentracijama arsena te masom adsorbensa, a temperatura u tom slučaju nije utjecala na rezultate. Dulje vrijeme adsorpcije nije utjecalo na količinu uklonjenog arsena, dok su niže pH-vrijednosti pogodovale adsorpciji istoga.
Abstract (english)
The toxicity of arsenic has been known for decades, and recently its carcinogenicity has also been proven. A large number of researches have been carried out linking increased concentrations of arsenic in drinking water with skin cancer, lung cancer and other types of cancer. Thus there is a growing interest in exploring methods of removing or reducing the concentration of arsenic in water, which is resulting in the improvement of existing and introduction of new technologies in water treatment. The aim of this master thesis was to examine the adsorption of arsenic on activated carbon which is produced by carbonization of hazelnuts shells and modified by saturation with iron(III) chloride. The efficiency of arsenic removal from water was monitored in relation to the initial arsenic concentration, adsorption time, pH and mass of the adsorbent. The dependence of mentioned parameters was monitored in correlation with temperature, so the experiments were performed in a thermostatted shaker. Research results showed that the percentage of the removed arsenic is proportional to the initial arsenic concentrations and the mass of adsorbent, but in this case temperature did not affect the results. Extended period of adorbtion also did not affect the amount of removed arsenic, while lower pH favored the arsenic adsorption.
