“…The use of high pressure in the extraction process allows the solvent to be kept in a liquid state when the temperatures being used are at or above the boiling point. It also improves the extraction efficiency by forcing the solvent into areas that would not normally be contacted under atmospheric conditions (Richter et al, 1996;Giergielewicz-Mozajska et al, 2001). A temperature of 100°C was chosen for ASE of the tested pesticides from rice over a temperature of 120°C because it resulted in recoveries of >98% (Fig.…”

“…The same quantity of rice (2 g) and the conditions previously established were used for both sizes. There was little difference temperatures will increase solubility and mass transfer, but decrease selectivity (Giergielewicz-Mozajska et al, 2001); therefore, the matrix components are coextracted. Considering the fact that rice has an elevated content of starch and other components highly soluble in organic solvents at high temperatures, it is feasible that under these extraction conditions their solubility is higher than the solubility of the target pesticides, resulting in the saturation of the solvent and a low content of the pesticides in the solution.…”

“…2. At elevated temperature and pressure, the PLE extraction process proceeds faster but selectivity decreases [98] Conventional SPE phases used in residue analysis and their characteristics are described in Table 1. However, these are being replaced more and more by polymeric sorbents that offer advantages for analytes that are difficult to purify on conventional phases shown in Table 2 [104].…”

“…A elevada pressão também facilita a extração já que força a penetração do solvente em áreas da matriz que não seriam alcançadas sob pressão atmosférica, tornando, desta forma, os analitos disponíveis para extração (RITCHER et al, 1996;GIERGIELEWICZ-MOZAJSKA et al 2001). Com exceção dos aspectos citados anteriormente, pouco ou nenhum efeito foi observado em decorrência de alterações na pressão empregada em diferentes aplicações, contanto que o solvente seja mantido no estado líquido (COSTA et al, 2010).…”
