Abstract
Salicilna kiselina je prirodni metabolit u biljkama, i njezinom modifikacijom mogu se dobiti njezini derivati, salicilati, koji se najčešće koriste u medicinske svrhe. Najpoznatiji predstavnik salicilata je acetilsalicilna kiselina, odnosno aspirin. Kao i mnogi derivati salicilne kiseline i acetilsalicilna kiselina sadrži protuupalna svojstva te je široko rasprostranjena. Izolacija salicilne kiseline započela je još u 19. st. kada se smatralo kako kora vrbe ima protuupalna djelovanja. Tijekom godina porasla je popularnost salicilne kiseline zbog njezinih raznih primjena te su se krenule razvijati metode za njezino određivanje te za određivanje salicilata. Zbog povećane popularnosti salicilne kiseline povećala se i konzumacija, čime raste potreba za određivanje njezine koncentracije u okolišu, vodama i proizvodima. U ovom radu obrađeno je pet najkorištenijih metoda kojima se može odrediti prisutnost salicilne kiseline i njezinih derivata. Najkorištenije metode su: kolorimetrija, spektofluorimetrija, tekućinska kromatografija visoke razlučivosti obrnutih faza, potenciometrija i voltametrija.
Abstract (english)
Salicylic acid is a natural metabolite in plants, and its modifications can be used to obtain its derivatives, salicylates, which are most often used for medical purposes. The most famous representative of salicylates is acetylsalicylic acid, i.e. aspirin. Like many derivatives of salicylic acid, acetylsalicylic acid also contains anti-inflammatory properties and is widely distributed. Salicylic acid was isolated back in the 19th century, when it was believed that willow bark has anti-inflammatory effects. The popularity of salicylic acid increased due to its various applications, and methods for its determination and for the determination of salicylates began to develop. Due to the increased popularity of salicylic acid, its consumption has also increased, which increases the need to determine its concentration in the environment, water and products. In this paper, the five most commonly used methods for determining the presence of salicylic acid and its derivatives are discussed. These methods are: colorimetric determination, spectrofluorimetry, liquid chromatography with high resolution of reversed phases, potentiometry and voltammetry.
