Optimization of ultrasonic extraction of 23 elements from cotton was performed with different solvent volume ratios. For this purpose nitric acid, hydrochloric acid and water were mixed and applied in a mixture for the extraction of elements adsorbed on cotton material. The elements chosen for the extraction procedure (Al, As, Be, Bi, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Mo, Na, Ni, Pb, Sb, Si, Sn, Tl and Zn) were those that are important in textile processing. Some of them cause problems during fiber processing, dyeing or bleaching. The removal of elements from the processed fabric can be successfully done with ultrasonic extraction in the ultrasonic bath. Extraction procedure was optimized by software package Design Expert 6 (DX6) and the optimum of ultrasonic extraction was achieved with the mixture of 1M HCl-1M HNO(3)-H(2)O=3.32/2.83/93.85 (v/v). Ultrasonic extraction was a fast and efficient extraction procedure easily applied on cotton textile material.
通过不同的溶剂体积比，对从棉花中超声提取23种元素的方法进行了优化。为此，将硝酸、盐酸和水混合，并用于提取吸附在棉花材料上的元素。选择用于提取过程的元素（铝、砷、铍、铋、钙、镉、钴、铬、铜、铁、汞、钾、镁、锰、钼、钠、镍、铅、锑、硅、锡、铊和锌）是那些在纺织加工中很重要的元素。其中一些元素在纤维加工、染色或漂白过程中会引发问题。在超声浴中通过超声提取可以成功地从加工过的织物中去除这些元素。提取过程通过软件包Design Expert 6（DX6）进行了优化，超声提取的最佳条件是1M盐酸-1M硝酸-H₂O = 3.32/2.83/93.85（v/v）的混合物。超声提取是一种快速高效的提取方法，易于应用于棉纺织材料。
