ZSM-5分子筛吸附水中苯胺的性能及应用

open access: yesGongye shui chuli, 2007
研究了高硅ZSM-5分子筛去除水中苯胺的效果,模拟废水的静态试验结果表明:ZSM-5分子筛对苯胺的吸附速率非常快,吸附时间为5min时,吸附率>90%;当分子筛用量为8g/L时,水中苯胺的吸附率可达95.7%;随着pH的增加,苯胺在沸石上的吸附率增大;温度增加,吸附率有所增加,但即使在常温下,苯胺的吸附率也能达到96%;ZSM-5分子筛对苯胺的最大吸附量可达37.3225mg/g,其吸附规律较好地符合Langmuir吸附等温式。对实际苯胺废水的处理结果也表明ZSM-5分子筛不仅可有效地去除苯胺 ...

f–f Transition in Er(OH)3 Promotes Photosynthesis of H2O2 Coupling With Oxidation of Benzylamine Over Sodium Poly(heptazine imides)

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT f–f electronic transitions of rare‐earth elements typically exhibit unique physicochemical properties that benefit the photocatalytic performance of the catalysts containing the elements. Although conventional rare‐earth metal oxides or single‐atom doping in semiconductors have been extensively studied, the construction of heterojunction ...

Bifunctional Competitive Structure of Biomass Carbon‐Derived Metacomposites for Tunable ε′‐Near‐Zero and ε′‐Negative Responses

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Regulating negative parameters of metacomposites is mainly limited by their unclear mechanisms, which affects their practical applications in new sensing, communication, electromagnetic (EM) protection and other fields. This work proposes a dual‐functional competitive design strategy based on the waste corncob‐derived carbon/polyaniline ...

Micro‐Macro Regulation Through Co‐Intercalation of Inorganic–Organic for the V2O5·nH2O Cathode Toward High‐Performance Aqueous Zinc‐Ion Batteries

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Vanadium oxides are deemed competitive cathode candidates for aqueous zinc‐ion batteries (AZIBs), benefited from their high theoretical capacity and multiple crystalline structures. However, the sluggish reaction kinetics, poor reversibility, and high solubility have hindered the practical application.

Topical and transdermal botanical formulations of the Chinese pharmacopoeia—A review

open access: yesPhytotherapy Research, Volume 38, Issue 9, Page 4716-4735, September 2024.
Abstract In pharmaceutics, ingredients are classified as active ingredients and excipients. In topical/transdermal phytomedicines, an ingredient may serve both functions. Published information on these dual‐purpose ingredients and their pharmacological relevance is limited.

臭氧氧化与生物法联合处理苯酚和苯胺废水研究

open access: yesGongye shui chuli, 2015
采用臭氧氧化、活性污泥法以及臭氧氧化与活性污泥联用法分别处理苯酚及苯胺废水。结果表明,这3种方法都能去除废水中的有机物,但单独臭氧氧化主要将苯酚和苯胺转化成中间产物,并不能将它们彻底矿化成二氧化碳和水。未经臭氧氧化直接进行活性污泥处理,1 h后苯酚和苯胺的去除率达到60%左右。臭氧氧化1 h与SBR活性污泥法曝气1 h对苯酚和苯胺的去除率可达95%以上。

UV/Fe0处理对硝基苯胺废水的研究

open access: yesGongye shui chuli, 2012
对UV/Fe0 协同降解对硝基苯胺废水进行了研究,分别考察了铁粉量、pH、对硝基苯胺初始浓度以及反应时间等影响因素对废水降解效果的影响。结果表明,对于50 mg/L 对硝基苯胺废水溶液,pH=3 时,当加入30 mg/L的铁粉量,反应180 min 后,对硝基苯胺降解率达到了93%。通过对比实验,发现UV/Fe0 体系较UV/Fe2+体系对对硝基苯胺具有更好的降解效果。

无机离子对电Fenton法处理苯胺废水的影响探究

open access: yesGongye shui chuli, 2020
通过实验考察了不同无机离子对三维电极体系耦合电-Fenton法处理苯胺废水效果的影响。实验发现适当浓度的Fe3+可促进苯胺的降解,Mn2+、S2-、CO32-、H2PO4-、Cl-则在一定程度上抑制了苯胺降解。NO3-对降解苯胺的影响并不明显。实际工程中,可根据不同无机离子对Fenton法影响程度,采取相应的预处理措施,保证苯胺废水处理效果。

铁碳微电解+水解酸化+BAF工艺处理苯胺废水

open access: yesGongye shui chuli, 2019
江西某企业主要生产N-取代苯胺类系树脂促进剂,产生的废水含较高浓度的COD和苯胺类化合物,难生物降解,单一的生化处理工艺难以达到排放标准。采用铁碳微电解+混凝沉淀+水解酸化+BAF组合工艺处理苯胺类生产废水,运行结果表明:系统运行稳定,COD总去除率为97.6%,苯胺总去除率为99.6%,出水COD≤100 mg/L,苯胺≤1 mg/L,出水达到GB 8978—1996《污水综合排放标准》一级排放标准。工艺处理成本为2.68元/m3。

选择性生物强化处理苯胺与易降解基质共存废水

open access: yesGongye shui chuli, 2014
向序批式活性污泥反应器中投加对甲苯胺降解菌(Stenotrophomonas sp. AT1-3),强化易降解有机物蔗糖与对甲苯胺共存废水中对甲苯胺的生物降解。研究结果表明:生物强化有助于提高污泥沉降性,并引起pH的急剧下降。电导率和TDS的下降趋势具有一定的对应关系。生物强化能提高对甲苯胺降解率。试验中强化组出水中对甲苯胺浓度远低于对照组,去除率由40%提高到70%以上,且在研究的近百个周期内效果保持稳定。
