As amostras de vanádio reagem com o extrato do reagente de tântalo na presença de ácidos fortes. Como se pode remover o complexo de cor rosa-pêssego que é formado? Existem alguma maneira viável de fazê-lo? Obrigado!

A proporção do extrato está incorreta ou há algum problema com o reagente

O método padrão nacional, o extrato não tem nenhum problema
