Factorial design-assisted spectroscopic determination of oxybutynin hydrochloride

Royal Society Open Science, 2021
In this study, we have developed two facile spectroscopic methods for quantifying oxybutynin (OBT) hydrochloride in its pure form and tablets using design of experiments (DOEs). The spectroscopic methods depended on the ion-pair complex formation between

Aplicação de planejamento fatorial a protocolo de extração e fixação de sulfetos volatilizáveis por acidificação (SVA) em amostras de sedimento Factorial design used on the extraction and fixation of acid volatile sulfides (AVS) from sediment samples

Química Nova, 2009
The AVS is defined operationally as acid volatile sulfide, which is a controlling phase on the partition of some metallic species in sediments. A Factorial design was evaluated by means of 16 experiments and using four variables: temperature, extraction ...
