The large pore molecular sieves VPI-5 and Si VPI-5 were synthesized by using three organic amines (dipropylamine, diisopropylamine and dipentylamine) as the str
The chemiluminescence reaction between luminol and reductant was investigated by a flow-injection system. The results show that this reaction can be used for th
