Gongye shui chuli, 2015 用KOH对市售的粉末活性炭进行表面改性。采用BET分析改性前后活性炭的表面结构,并采用活性炭涂层电极构建电容去离子吸附装置,研究改性后电极的去离子效果。研究表明:经过KOH改性后,活性炭的比表面积从519.25 m2/g增加到975.07 m2/g,提高了87.78%,中孔孔容占总孔孔容的百分比提高了48.28%,改性后活性炭的孔隙结构和孔径的分布更有利于溶液中的Na+和Cl-通过,提高了电极的吸附速率。

World Water Policy, Volume 12, Issue 3, August 2026.ABSTRACT Groundwater depletion is a major challenge in semiarid, hard‐rock regions where irrigation demands often exceed natural recharge. This study evaluates the effectiveness of farm‐scale recharge pits as a local, supplementary, and community‐managed groundwater recharge solution in the Dharta catchment of Rajasthan, India. Alongside check dams and

Organ‐specific ozone and nitrogen legacies strengthen substrate control over litter decomposition
Functional Ecology, Volume 40, Issue 8, Page 2548-2559, August 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Elevated tropospheric ozone (O3) and nitrogen (N) deposition are concurrent atmospheric changes that strongly influence terrestrial carbon cycling, yet their combined effects on below‐ground decomposition remain poorly understood.

Gongye shui chuli, 2013 研究了硝酸改性活性炭(AC)催化微波(MW)照射降解水中结晶紫的方法。探讨了改性液浓度、改性时间、MW照射时间、催化剂用量和结晶紫溶液初始浓度等因素对降解的影响。结果表明,改性AC催化活性高于未改性AC。对于25.0 mL 100 mg/L结晶紫溶液,当改性AC质量浓度为2.0 g/L,MW照射3.0 min时,降解率为94.6%。通过提高催化剂用量至2.4 g/L或延长照射时间至4.0 min,降解率分别可达98.2%和100%。此法适合于染料废水的处理。

Shuitu Baochi Xuebao, 2021 为探究改性前后生物质炭的理化属性变化及其对邻苯二甲酸二乙酯（DEP）的吸附机理，以椰子壳和花生壳为原料制备生物质炭，分别进行14% H3PO4改性和1.0 mol/L NaOH-30% H2O2联合改性处理。结果表明：改性后生物质炭的芳香化程度和含氧官能团含量增加，除C300N （经NaOH-H2O2改性的300℃—椰子壳生物质炭）外比表面积（SA）都增大。P800N （经NaOH-H2O2改性的800℃—花生壳生物质炭）有最大的SA （584.22 m2/g），因此对DEP的吸附亲和力最高 ...

Abstract Root activity creates unique microbial hotspots in the rhizosphere by influencing the metabolic activities of surrounding soil microorganisms, profoundly regulating the dynamics of soil organic carbon (SOC). However, how root economic strategies affect the formation and

Conservation Biology, Volume 40, Issue 4, August 2026.Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Gongye shui chuli, 2003 研究了有机改性膨润土对石油废水中聚丙烯酰胺(PAM)的去除效果。实验结果表明:由溴化十六烷基三甲铵(CTMAB)阳离子改性的膨润土和双阳离子改性的膨润土对PAM的吸附等温线都符合Langmuir等温吸附曲线,改性膨润土的层间距的大小是影响饱和吸附量的一个重要因素,质量分数为7%的单阳离子改性膨润土对PAM的去除率可达到90%以上;双阳离子改性膨润土对PAM的饱和吸附容量随长碳链表面活性剂CTMAB的增加而增加。
