sido sais e óxidos <strong>de</strong> chumbo e cobre, não foi possível caracterizar nenhum<br />

complexo metálico com chumbo, o que não exclui a possibilida<strong>de</strong> <strong>de</strong> que o AMT<br />

tenha reagido com os compostos <strong>de</strong> chumbo formados.<br />

O AMT <strong>de</strong>monstrou ser eficiente para remover os produtos <strong>de</strong> corrosão do<br />

bronze estudados. O mesmo po<strong>de</strong> ser utilizado pelo restaurador <strong>de</strong> metais em<br />

situações nas quais as pátinas formadas não são estáveis e permitem a <strong>de</strong>gradação<br />

dos bens culturais e artefatos corroídos.<br />
