AVALIAÇÃO DE MÉTODOS CROMATOGRÁFICOS, ESPECTROSCÓPICOS E SCOTT COMO MÉTODOS PREDITIVOS PARA ANÁLISE E DETECÇÃO DE COCAÍNA

Abstract

A cocaína é um estimulante do sistema nervoso central. Seus adulterantes são substâncias usadas estrategicamente com o objetivo de aumentar lucros, ampliando ou emulando seu efeito estimulante e analgésico. Com o objetivo de avaliar os métodos de Scott, Cromatografia em Camada Delgada (CCD), Cromatografia gasosa acoplada à espectrometria de massas (CG-MS), Espectroscopia no infravermelho por transformada de Fourier (FTIR), Espectroscopia na região ultravioleta-visível (UV-Vis) e Ressonância magnética nuclear (RMN) como métodos preditivos para a análise e detecção de cocaína, foi feito um levantamento bibliográfico com 38 trabalhos relevantes da área a fim de comprovar a eficácia desses métodos. As técnicas supracitadas proporcionam nas análises forenses a eliminação de possibilidades de resultados falso positivos. Há desvantagens sob a técnica de Scott e CCD, por serem apenas colorimétricas. Constatou-se que as técnicas de CG-MS, RMN, FTIR e UV-Vis oferecem informações substanciais na etapa de investigação policial, ao obter-se o perfil químico das drogas apreendidas

Cocaine is a central nervous system stimulant. Its adulterants are substances used strategically to increase profits by enhancing or emulating its stimulant and analgesic effects. In order to evaluate the Scott methods, Thin Layer Chromatography (TLC), Gas Chromatography coupled to Mass Spectrometry (GC-MS), Fourier Transform Infrared Spectroscopy (FTIR), Ultraviolet-Visible Spectroscopy (UV-Vis) and Nuclear Magnetic Resonance (NMR) as predictive methods for the analysis and detection of cocaine, a bibliographic survey was conducted with 38 relevant studies in the area in order to prove the effectiveness of these methods. The aforementioned techniques eliminate the possibility of false positive results in forensic analyses. There are disadvantages to the Scott and TLC techniques, as they are only colorimetric. It was found that CG-MS, NMR, FTIR and UV-Vis techniques offer substantial information at the police investigation stage, when obtaining the chemical profile of the seized drugs
