Avaliação do perfil de dissolução de medicamentos utilizando-se espectroscopia eletrônica multivariada

Abstract: Recebido em 21/1/11; aceito em 3/5/11; publicado na web em 8/7/11 EVALUATION OF THE DISOLUTION PROFILE OF DRUGS BY MULTIVARIATE ELECTRONIC SPECTROSCOPY. In this work the evaluation of the dissolution profile of captopril-hydrochlorothiazide and zidovudine-lamivudine associations were carried out by multivariate spectroscopic method. The models were developed by partial least square regression from 20 synthetic mixtures using mean-centered spectral data. The external validation was accomplished with 5 synthetic… Show more

“…Thus, the remediation is probably one of the major challenges faced by researchers due to the dynamics between pollutants and medium as well as because some pesticides are persistent pollutants . The removal of pesticides from media has been attempted by using different techniques including advanced oxidative processes (AOPs), membranes technology, soil washing, and the use of adsorbents, such as activated carbon or biochar . All these techniques have some drawbacks that are essentially related to the high energy cost, the formation of by‐products (as it happens in, e. g ., AOPs) and membrane fouling; in turn, activated carbon is cheap and highly efficient as adsorbent for pollutant removal, but its reuse is difficult and expensive.…”
