膜富集-高强UV/SO₃^2-体系高效降解PFOS的研究

Gongye shui chuli, 2020
工业废水中全氟辛烷磺酸（PFOS）浓度低，直接应用化学法降解能耗较高。采用膜分离与UV/SO32-光降解的组合工艺对其进行处理，研究了此组合技术的处理效果，并考察了影响降解率的因素。结果表明，反渗透膜可有效富集PFOS溶液，高强UV/SO32-体系可高效降解该富集溶液。提高溶液初始pH、SO32-浓度、紫外光强，均有利于PFOS降解率的提高，而PFOS初始浓度的提高会降低其降解率。

对磺胺嘧啶厌氧生物降解机理的研究

Gongye shui chuli, 2021
以磺胺嘧啶为目标污染物，考察厌氧生物对磺胺嘧啶的降解性能。结果表明，在25℃、pH为6.0、外加100 mg/L碳酸氢钠的条件下，微生物对20 mg/L磺胺嘧啶的降解率为99.7%，磺胺嘧啶的降解过程符合零级反应动力学特征。降解途径分析显示，厌氧生物通过3条平行途径降解磺胺嘧啶，将磺胺嘧啶逐渐转化为低毒和无毒的化合物，其中2-氨基-4-羟基嘧啶是主要降解产物。

PVA降解混合菌系处理模拟废水试验

Gongye shui chuli, 2013
将筛选出的一种能完全降解PVA浆料的混合菌系应用于模拟废水的处理,考察了染料和淀粉对该PVA降解混合菌系的影响。结果表明,染料对混合菌系降解PVA的影响不大,混合菌系对所添加染料的去除率虽低于20%,但可起到降低后续处理负荷的作用;淀粉会影响混合菌系对PVA的降解效果,降解率下降至92%左右。

MoS2‐Modified Bamboo‐Like Nitrogen‐Doped Carbon Nanotubes Encapsulating Ni Nanoparticles Enabling Synergistic Adsorption–Catalysis for High‐Performance Lithium–Sulfur Batteries

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The commercialization of lithium–sulfur batteries (Li–S batteries) has been hindered by the shuttle effect of lithium polysulfides (LiPSs) and sluggish redox kinetics. In this study, we constructed a three‐dimensional hollow conductive network host material for sulfur with synergistic enhancement effects.

Revealing the Roles of Electrolyte Concentration on Transition Metal Dissolution and Reaction Pathway of Anion Adsorption Pseudocapacitance

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Conventional lithium‐ion battery cathodes predominantly rely on reversible lithium intercalation in bulk, which inevitably induces phase transitions, transition metal migration, and voltage decay. Electrolytic anion adsorption pseudocapacitance provides a chance for bypassing these issues via a surface‐dominated reaction, especially in ...

二沉池出水中双酚A的高铁酸钾氧化降解行为

Gongye shui chuli, 2011
考察了pH、温度、反应时间、浓度、光照、腐殖酸、干扰离子等因素对高铁酸钾降解双酚A的影响,并探讨了高铁酸钾降解双酚A的动力学机理以及对二沉池出水中双酚A的降解作用。研究表明:在pH=9.0,室温条件下,反应10 min后双酚A的降解率达最大值;光照对双酚A降解基本没有影响;腐殖酸对双酚A的降解有一定促进作用;干扰离子对双酚A降解影响较为复杂,既有促进作用又有抑制作用。以二沉池出水为基体,当m(高铁酸钾)∶m(双酚A)=5∶1,双酚A初始质量浓度为5.0 mg/L时,反应4 min后,双酚A的降解率达99%
