查询词典 acid value

The results showed that the amounts of base cations leached from calcareous soils and coastal solonchak were lower than the cation exchange capacity and the releasing amounts of Al3+ being lower than 0.40mmol·kg-1 all the way under the treatment of simulated acid rain with each pH value from 2.5 to 5.6,so the H+ buffering...

结果表明，石灰土和滨海盐土的阳离子淋溶量低于阳离子交换量，土壤主要处于阳离子交换缓冲范围和碳酸盐-硅酸盐缓冲范围，Al释放量一般低于0.40mmol·kg~(-1)，铁铝土纲系列土壤在阳离子释放总量超过阳离子交换量后，淋溶液pH值急剧下降，此时Al淋溶量明显增加，质子缓冲转向Al缓冲范围，其释放量决定于土壤富铁铝化程度的高低和活性Al含量的多少，紫色土在低pH模拟酸雨淋溶下，由于含大量硅铝率较高的易风化原生或次生矿物，盐基释放量高于CEC，但Al释放量未明显增加，淋溶液pH也较稳定，土壤尚处于矿物风化为主的硅酸盐缓冲范围。

There was a best numerical value of grinding time and quantity of stearic acid in orderto achieve the best modifying effect.

Molecularly imprinted polymers of sulfamethazine(SM 2 ) were prepared with silica gel as a sacrificial material, methacrylic acid and 4 vinylpyridine(4 Vp) as functional monomers, glycol dimethacrylate as crosslinker. The polymer properties were investigated by static adsorption experiments. Scatchard analysis shows that the adsorption ability of MAA MIP is superior to that of 4 Vp MIP. The dissociation constant of MAA MIP is 9 59×10 -4 mol/L. The value of apparent binding a...
