Removal翻譯（removals翻譯）

一、hair removal是什么意思

上面的都不對，這里的hair不是一般的頭發(fā)的意思，而是泛指體毛，除去面部毛發(fā)以外的毛發(fā)。因為女士毛多很不雅觀，故很多產(chǎn)品都是針對Hair Removal這一需求的，當(dāng)然也有專業(yè)的除毛店鋪。

注：removal是動詞remove的名詞形式。

二、dustremovalfilm是什么意思

dust removal film的中文翻譯

dust removal film

除塵膜

雙語例句

Feasibility Analysis of Dust Removal By Water Film Acoustic

Condensation

水膜式聲學(xué)凝聚除塵可行性分析

Research on the characteristics of flue gas dust removal and

desulfurization using double-recycling and multi-stage water film tower

Application of the Desalting System of the Cooling Water for the Vertical

Magnetic Separator in the Ore-dressing Plant

To enhance the adsorption efficacy of activated alumina, researchers have also modified alumina surface. In an effort to modify alumina, La(III)- and Y(III)- were impregnated to alumina by Wasay et al. [58]. The adsorption characteristics of the La(III)- andY(III) - impregnated alumina and the original alumina were compared for the removal of fluoride, and some other anions under various conditions. The removal selectivity by the impregnated alumina was found to be in the order: fluoride > phosphate > arsenate > selenite. Lanthanum hydroxide supported on alumina has also been studied to remove fluoride from aqueous solutions [59].

為了提升活性氧化鋁的吸附效果，研究人員也曾改良過氧化鋁的表面。根據(jù)Wasay與伙伴的研究[58]，他們以鑭（III）和元素釔（III）浸漬氧化鋁的方式以期改良氧化鋁。隨后將鑭（III）和元素釔（III）浸漬的氧化鋁和原鋁在各種條件下針對它們的除氟特性及某些其他陰離子進行對比。根據(jù)觀察，浸漬氧化鋁的遷移選擇性的順序如下：氟>磷>砷>硒。也有研究使用含氫氧化鑭的氧化鋁進行水溶液除氟[59]。

The adsorption capacity of original alumina was in the range of 0.170–0.190 mM/g, whereas for alumina impregnated with lanthanum hydroxide, the adsorption capacity was found higher (0.350 mM/g). The possible removal mechanism of fluoride by impregnated alumina was explained by ion exchange process between anion and hydroxide group on surface material. The adsorbent was effective in decreasing fluoride concentration from 7 mM to 0.003 mM in the pH range 5.7–8.0. Fluoride removal was affected by the presence of phosphate and sulphate whereas chloride, bromide, iodide and nitrate ions did not show significant influence on the sorption of fluoride by the prepared sorbent. The sorbed fluoride ions were eluted from the adsorbent with 10 mL of 0.1 M NaOH and the column could be reused after being conditioned with 10 mL of 1 mM HCl.

原氧化鋁的吸附容量的范圍是0.170–0.190 mM/g，而氫氧化鑭浸漬氧化鋁的吸附容量則較高(0.350 mM/g)。浸漬氧化鋁的除氟機理可以解釋為表層介質(zhì)的陰離子和氫氧化組的離子交換過程。在5.7至8.0 pH值之間，吸附劑可以有效地將氟濃度從7 mM 降至0.003 mM。

磷酸鹽和硫酸鹽的存在影響除氟作用，而氯化、溴化、碘化和硝化離子卻沒表現(xiàn)出對吸附劑的吸氟作用有明顯的影響。被吸附的氟離子可以用10 mL的0.1 M氫氧化鈉從在吸附劑上洗提下來，經(jīng)過用10 mL的1 mM鹽酸護理后，塔還可重新使用。

Tripathy et al. [60] also modified the alumina surface by impregnating with alum and used the modified adsorbent for defluoridation. The adsorption of fluoride increased with the rise in pH and reached a maximum of 92.6% at pH 6.5, and then decreased with further increase in pH. Fluoride removal decreased in acidic range due to the formation of weak hydrofluoric acid or combined effect of both chemical and electrostatic interaction between the oxide surface and fluoride ion. At pH above 6.5, fluoride removal decreased sharply due to stronger competition with hydroxide ions on the adsorbent surface. The Langmuir sorption capacity of fluoride was found to be 40.68 mg/g at pH 6.5. Energy-dispersive X-ray spectroscopy (EDAX) analysis provided direct evidence that fluoride was superficially adsorbed on alum impregnated activated alumina (AIAA) and the reaction might not be due to the adsorption, but simply surface precipitation. The desorption of fluoride from the adsorbent was done by rinsing the fluoride-adsorbed AIAA with 0.1 M NaOH at pH 12.0 followed by neutralization with 0.1 M HCl.

Tripathy與伙伴的研究[60]也利用明礬來改良氧化鋁的表面來進行除氟。吸氟力隨著pH值的升高而增強，當(dāng)pH值在6.5時，吸氟力最高可達92.6%，過后吸氟力將會隨著pH值的繼續(xù)升高而下降。在酸性范圍內(nèi)除氟力的下降是因為弱氫氟酸的形成，或者是氧化表面和氟離子的化學(xué)與靜電的相互作用。除氟力在pH值高于6.5時大幅下降是因為在吸附劑表面的氫離子較強的競爭。Langmuir氟吸附容量在6.5 pH值是40.68 mg/g。根據(jù)能量擴散式X射線光譜（EDAX）分析所提供的直接證據(jù)，氟被吸附于明礬浸漬氧化鋁（AIAA）的表面，這種反應(yīng)可能不是吸附作用，而只是表面沉淀。用pH值12.0 的0.1 M氫氧化鈉清洗附有氟的明礬浸漬氧化鋁，然后以0.1M鹽酸進行中和，就可把氟從吸附劑脫附下來。
