通过一次平衡法考察了pH、离子强度和溶剂介电常数对红壤吸附低分子量有机酸的影响。研究结果表明,随着溶液pH值的升高有机酸的吸附量降低,其中草酸和酒石酸的吸附量在pH3.5~5.0范围内随着pH值的升高而急剧下降,之后缓慢下降(pH5.0~7.0)。柠檬酸、酒石酸和苹果酸的吸附量在1~2mmol/L初始浓度范围内随着离子强度的增加没有明显变化,但在2~20mmol/L初始浓度范围内却随着离子强度的增...

信阳佳鑫膨润土厂 产品 活性白土
2012/3/27
信阳佳鑫膨润土厂生产的该产品选用信阳优质的膨润土为原料，经过精选、活化挤压、烘干、研磨等一系列工序，生产出高效活性白土。该产品以白色和粉红色为主，无臭无味，无毒，活性较好，吸附性强，在空气中容易吸潮，如放置太久或受潮会降低其吸附功能，使用时宜加热（以80—100度为宜）复活，若加热至300度以上开始失去结晶水，本身结构发生变化，影响脱色效果。
