概括

来自废物材料的生物炭 (BC) 有效地从废水中回收性物质 (HSs). 来自草的BC显示了最高的HS回收率,表明了可持续的土壤修改和污染物固定化的潜力.

科学领域:

环境科学环境科学
土壤科学土壤科学
废物管理废物管理

背景情况:

生物炭 (BCs) 越来越多地通过热解从各种废物流中产生,用于土壤修改.
与其他有机修改剂相比,BCs提供了优越的土壤稳定性和营养吸收.
从废水中回收化物质 (HSs) 是至关重要的,因为化肥资源是不可再生的.

研究的目的:

为了评估十种不同的生物炭 (BCs) 从无氧消化中回收性物质 (HSs) 的潜力,拒绝水 (RW).
为了确定最佳的BC类型和用于高效的HS回收的热解条件.
评估HS恢复BCs作为土壤修改物的适用性.

主要方法:

十个BCs是由松树,树,草,向日和在不同热解温度下消化而产生的.
从RW中恢复HS是使用24小时接触方法实现的.
用光谱光度计量HS吸收能力.

主要成果:

在低热和高热解温度下从中获得的BCs表现出最高的HS吸附能力 (分别为3.10和5.31毫克g-1).
来自向日 (所有温度) 和树 (高温) 的BCs被确定为非常有前途的吸附剂.
热解温度显著影响了来自同一生物质来源的BCs的HS吸收能力.

结论:

废弃物衍生的生物炭,特别是来自草的生物炭,有效地从废水中回收有价值的性物质.
选择的BC显示了双重应用的潜力:HS恢复和土壤质量提升.
需要进一步的研究来验证在不同土壤条件下BC的性能,并评估它们对植物健康的长期影响.

关键词:

生物炭是一种生物炭.富尔维酸是一种富尔维酸.胺酸是胺酸中的一种.吸附吸附方式吸附吸附方式紫外线 UVVis 的使用.

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Factors Affecting Solubility

Factors Affecting Solubility

Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:

Coagulation

Coagulation

Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...
