赤泥/煤基铁炭材料的制备及其脱除废水Cr(Ⅵ)的性能
, 2018 以脱钠赤泥、粉状褐煤为原料,羧甲基纤维素钠为黏结剂,采用碳热还原法制备了可替代商业铁炭微电解填料的廉价铁炭材料,用于去除废水中的Cr(Ⅵ)。考察了不同的制备参数(炭化温度、炭化时间、赤泥/煤质量比)和吸附条件(溶液pH、浓度),以提升Cr(Ⅵ)去除效果。结果表明质量比(赤泥/煤)为1/3、800℃炭化1h的赤泥/煤基铁炭材料,可达到最大Cr(Ⅵ)吸附量(4.03 mg·g~(-1))、最低铁溶出量(许光文, 余剑, 仇雅丽, 李文松, 高士秋, 李长明, 王德亮 +6 morecore 不同种类活性炭对mZVI/活性炭吸附还原Cr（Ⅵ）的影响
Gongye shui chuli基于活性炭（AC）的良好吸附性能和其可与微米零价铁（mZVI）结合形成微电解体系的特性，采用球磨法（BM）合成多种mZVI/ACs复合材料，并探讨该类材料对Cr（Ⅵ）的去除效能，对最佳复合材料去除Cr（Ⅵ）的机理进行解析。研究结果表明，BM可使AC与mZVI有效结合，短时球磨条件下mZVI/AC（木质）对Cr（Ⅵ）的去除效果较优。溶液中的Cr（Ⅵ）主要由次生Fe2+还原，而AC不仅可加强mZVI/AC对Cr（Ⅵ）的吸附，而且还促进了mZVI的腐蚀，进而强化了对Cr（Ⅵ）的去除。通过监测Cr（Ⅵ ...王文豪, 程业兴, 王雨银, 侯婷婷, 吴晓峰, 李玉才 +5 moredoaj 低温低浊水中聚硫氯化铝应急处置Cr(Ⅵ)的实验
Gongye shui chuli, 2018 近年来，我国频发水环境突发污染事件，给生产生活造成巨大影响。在低温低浊条件下探究了不同混凝剂对Cr（Ⅵ）的去除效果，并以聚硫氯化铝（PACS）为混凝剂，考察pH、PACS投加量、PAM投加量、静置时间、Cr（Ⅵ）初始质量浓度对Cr（Ⅵ）去除效果的影响。结果显示，PACS的去除效果优于其他混凝剂，在pH为8、PACS投加量为200 mg/L、PAM投加量为6 mg/L、静置时间为30 min条件下，Cr（Ⅵ）去除率可达91.7%，PACS的混凝效果随Cr（Ⅵ）质量浓度的增大而下降。投加PACS可实现对Cr（陈齐玮, 陈思莉, 常莎, 陈鼎豪, 易仲源, 王骥, 潘逸超, 虢清伟, 熊正为, 陈尧 +9 moredoaj Fluorescence Quenching Method for the Determination of Trace Chromium(Ⅵ)
, 1999 [中文文摘]本文研究了用荧光猝灭法测定痕量六价铬。本方法是基于六价铬与碘化钾反应生成了单质碘,碘可以使2’,7’-二氯荧光素(DCF)发生荧光猝灭,从而间接测定六价铬。六价铬浓度在0.20-2.50μAg/25ml范围内,荧光强度差值与六价铬浓度呈线性关系,线性回归方程△F=12.12C+0.19,相关系数γ=0.9993,检测限为0.1μg/25mL。本法简便、灵敏度高,已用于合成样中六价铬的测定,回收率在100～103％,结果令人满意。[英文文摘]A simple and sensitive ...林清赞, 范宝玲(福建省农科院生物中心), 傅明来(福建省连城锰矿中心化验室), 许金钩 +3 morecore Cumulative Social Disadvantage and Disease Activity in Juvenile Idiopathic Arthritis: A Childhood Arthritis and Rheumatology Research Alliance Registry Study
Arthritis Care &Research, EarlyView.Objective
Social determinants of health (SDOH) contribute to juvenile idiopathic arthritis (JIA) disparities, but most studies have assessed SDOH independently rather than cumulatively across individual, family, and neighborhood levels. Using a socioecological framework, we investigated the relationship among cumulative social disadvantage ...William Daniel Soulsby, John Boscardin, Andrea Knight, Daniel B.
