美 { "us": "", "uk": "" }
英 { "us": "", "uk": "" }
数据源: ai_enrichment
指物质(如气体或液体)被固体表面吸引并附着在其上的状态,常用于化学或物理领域。

用法要点

被动语态使用

通常以被动语态出现,描述物质被吸附的过程或状态,强调固体表面的作用。

• be adsorbed onto
• get adsorbed by
• remain adsorbed

介词搭配

常与介词“onto”或“by”连用,表示吸附到某表面或被某物质吸附,在学术语境中更精确。

• adsorbed onto the surface
• adsorbed by activated carbon
• adsorbed in the pores

语域说明

主要用于科技、化学、环境科学等专业领域,日常口语中较少使用,属于正式或学术词汇。

• adsorbed pollutants
• adsorbed molecules
• adsorbed layer

基础例句

The moisture in the air gets adsorbed by the silica gel packets in the box.

空气中的湿气被盒子里的硅胶包吸附了。

When you spill oil, it can be adsorbed onto paper towels for cleanup.

油洒出来时,可以用纸巾吸附来清理。

The activated carbon in the filter has adsorbed many impurities from the water.

过滤器中的活性炭吸附了水中的许多杂质。

高级例句

In environmental engineering, pollutants are often adsorbed onto activated carbon for removal from wastewater.

在环境工程中,污染物常被吸附到活性炭上,以便从废水中去除。

The research shows that CO2 molecules can be strongly adsorbed by certain metal-organic frameworks at high pressures.

研究表明,二氧化碳分子在高压下能被某些金属有机框架强烈吸附。

In catalysis, the reactants must be adsorbed onto the catalyst surface before the reaction can proceed efficiently.

在催化过程中,反应物必须先被吸附到催化剂表面,反应才能高效进行。

常见错误

❌ 错误:The water is adsorbing the dirt.
✓ 正确:The dirt is adsorbed by the sponge.

错误:误用主动语态,且主语应为被吸附物。正确:使用被动语态,强调污垢被海绵吸附的过程。

❌ 错误:It adsorbed on the wall.
✓ 正确:It is adsorbed onto the wall.

错误:缺少助动词,且介词使用不准确。正确:添加“is”构成被动语态,并用“onto”表示吸附到表面。

近义词辨析

absorbed

“absorbed”指物质被整体吸收或融入内部(如液体被海绵吸收),而“adsorbed”特指物质附着在表面。

Water is absorbed by the sponge (进入内部), but pollutants are adsorbed onto the filter surface (附着表面).

attached

“attached”泛指连接或固定,可用于物理或抽象场景;“adsorbed”是科技术语,专指通过物理或化学力在表面附着。

The document is attached to the email (一般连接), while ions are adsorbed onto the electrode (表面吸附).
