The principle of solidification sludge strength because of clay mineral is not clear and has not supported the choice of clay mineral. The mineral and pore water is analyzed in order to contrast clay mineral added or not based on the XRD and pore water chemical character. The result shows that the absorbed quantity of Ca2~ was reduced by sludge because of clay mineral added, the hydrated reaction was advanced and integrated solidified materials was formed.展开更多

Hydroxylamine sulfate and hydrated hydrazine can react with BrO to produce Br-. They show some analogies with vitamin C in their effects on B-Z reaction, that is, they sbolarly lengthen the induction period and oscillating period,and shorten the life-span of this oscillating reaction.From this reason the conjecture of reaction mechanism that is proposed by Zhao Xuezhuang et al can be confirmed.展开更多
