Zhongguo youzhi旨在为大豆油精炼中脱色剂的应用提供参考，以大豆碱炼油和3种常用脱色剂活性白土、凹凸棒土、中性膨润土为原料，考察了3种脱色剂对大豆油的脱色、脱皂和脱磷脂能力。结果表明：活性白土、凹凸棒土、中性膨润土添加量超过2%后，脱色率上升速率变慢；脱色剂添加量为3%时，活性白土、凹凸棒土、中性膨润土脱色率分别为92.1%、86.9%、90.7%；大豆碱炼油在426、450、479、665 nm波长处有吸收峰，可通过油样在上述4个波长处吸光度的变化来考察脱色剂的脱色能力;脱色剂添加量为1%时，活性白土、凹凸棒土 ...

Gongye shui chuli, 2003 使用还原型脱色剂对直接染料染色废水进行脱色处理，重点研究了脱色剂用量、反应温度、pH和时间等因素对脱色反应的影响。并且将脱色后的染色废水回用于织物染色中，在染色织物的颜色特征和牢度方面进行了比较。结果表明，脱色温度的升高有利于染料的脱色，尤其对于水溶性较差的品种，脱色剂用量的增加能够促进染料的脱色率的升高。另外三种染料在自来水和回用水中的的染色织物的染色表面深度和牢度比较接近，而且染色织物之间的色差较小，这说明脱色废水可以回用于直接染料的染色中。

Gongye shui chuli, 2010 就粉末活性炭和大孔树脂对苯酐酸水的脱色效果进行了研究。首先考察了活性炭种类、脱色时间、活性炭用量等因素对脱色效果的影响,结果表明在优化后的条件下其对苯酐酸水的脱色率仍难以达到90%。此后通过试验筛选了4种脱色用大孔树脂,发现SXD-11树脂具有较好的脱色效果。在实验条件下,流出液体积为5 BV时的酸水脱色率在95%以上,10 BV时的脱色率<85%。针对工业应用,最后在活性炭脱色基础上构建了与树脂脱色相联合的分步脱色法。该分步脱色法不仅保证了流出液体积20 BV时总的脱色率保持在91%以上 ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT LiBH4 has drawn significant attention due to its high theoretical hydrogen storage capacity of 18.5 wt%, yet its practical application is hindered by the harsh dehydrogenation conditions. This paper proposes a strategy integrating ensemble learning with density functional theory (EL–DFT) for rapidly screening modified LiBH4 systems that ...

蒙脱土对植物油脱色效果的综合评价Comprehensive evaluation of the bleaching effect of montmorillonite on vegetable oil
, 2022 为了开发高效、环保的食用油脱色剂，以一种环保方法（半干法）生产的蒙脱土为研究对象，研究其在不同脱色条件（脱色温度、脱色时间和脱色剂添加量）下对大豆油、葵花籽油和菜籽油品质的影响。结果表明：该蒙脱土具有吸附色素和过氧化物从而降低油脂红值和过氧化值的作用，与脱色前相比，大豆油、葵花籽油和菜籽油的红值最大降幅分别为77.4%、92.3%和87.2%，过氧化值最大降幅分别为82.7%、83.2%和91.2%；蒙脱土用于3种植物油的脱色，植物油中总甾醇和总生育酚含量下降，而酸值总体上缓慢上升。进一步研究发现 ...

People and Nature, Volume 8, Issue 3, Page 741-753, March 2026.Abstract Currently, scholarship on education to foster connectedness with nature primarily focuses on children. As adults likewise face the disconnection from nature and play a key role in influencing children, it is important to understand how they perceive, engage in, and benefit from relevant programmes.
