Abstract

U ovom radu adsorbens je fotokatalizator pripravljen od brusnog papira koji služi kao nosač na koji je nanešena smjesa titanijeva (IV) oksida i procola, a adsorbat je insekticid acetamiprid. Svrha samog rada je izučavanje adsorpcije insekticida acetamiprida na površinu fotokatalizatora kako bi se acetamiprid uklonio u što većoj mjeri iz otopine, što predstavlja korak prije fotokatalitičke razgradnje. Proces adsorpcije odvijao se u reaktoru (čaši) na dnu kojeg je bio pripravljeni fotokatalizator, a otopina acetamiprida je stalno recirkulirala pomoću pumpe. Adsorpcija se provodila pri različitim uvjetima koncentracije, protoka i pH otopine acetamiprida pri čemu je praćen utjecaj tih parametara na proces adsorpcije, a otopina je uzorkovana u danim vremenskim intervalima kroz 60 minuta te analizirana na HPLC (engl. high performance liquid chromatography) uređaju.

Abstract (english)

In this paper, the adsorbent is a photocatalyst prepared from sandpaper, that serves as a carrier on which a mixture of Titanium (IV) oxide and Procol is applied, and the adsorbate is an insecticide acetamiprid. The purpose of this paper is to study the adsorption of acetamiprid insecticide on the surface of the photocatalyst in order to remove the acetamiprid from the solution as much as possible, which is a step previous to the photocatalytic degradation. The adsorption itself took place in a reactor (a beaker) at the bottom of which a photocatalyst was prepared and the acetamiprid solution was constantly recirculated with the help of a pump. Adsorption was performed under different conditions of concentration, flow and pH of acetamiprid solution, monitoring the influence of these parameters on the quality of adsorption, then the solution was sampled at given time intervals throughout 60 minutes and analysed on HPLC (high performance liquid chromatography) device.
