Abstract
There is a great number of packaging materials, such as bottles and boxes, are made of plastics (polymers). Additives such as plasticizers, antioxidants, antistatic agents, and lubricants may be used for the production of packaging materials. The worst effect of plastic production is deterioration of the environment. Recycling solves this problem and the initial step is identification and classification of the polymers and determination of different elements present in it. In this research, spectroscopic analyzes were performed using Laser Induced Breakdown Spectroscopy (LIBS) for plastic materials samples of drug containers that collected from manufacturing factories located at Khartoum city, Sudan. The samples were collected before and after used, were irradiated by Nd: YAG laser at 266 nm, repetition rate 2Hz, with pulse energy of 80mJ. The recorded spectra of the samples were analyzed using National Institute Standard and Technology (NIST). and Origin Lab Pro 9 data analysis software. All elements present in plastic drug bottles were detected using laser induced breakdown spectroscopy. The elements that detected are (Ca, Cd , Ra, Ac, W, V, Na, Pm, Cl, K, , Ce, Ar, Nd, Ac, Tc, Sc, Li, Pa, and Pb).
