Abstract

In this study, removal of the Penicillin G antibiotic by using algae (Sargassum angustifolium) and the effects of algae concentration parameters (one in a thousand and two in a thousand), pH of solution (5, 7.5 and 8.5), contact time (1, 3, 9 and 27 hours), soluble temperature (17 and 27 º C) were studied. Initial concentration of the Penicillin G was 25 mg/L. The maximum adsorption efficiency was obtained at the exposure time of 27 hours, pH 8.5 and 27 º C and with the values of 31.56% and 36.92% in concentrations of one and two in 1000. According to the results of time (F= 10449.01) and temperature (F = 1046.06) the most efficient parameters involved in the removal of penicillin were by algae. The output of the regression analysis with the modified coefficient (Adj R2) 0.817 and F equals to 69.93, from the Y= 28.45- 0.39X1-0.19X2 -0.09-X3- 0.83X4. The present study showed that the microalgae (Sargassum Angustifolium) is a suitable and efficient adsorbent for the removal of antibiotics from aqueous solutions, which is due to its indigenous and access to it, it is possible to exploit it as a natural adsorbent in filtration systems.
