This study aims to optimize the treatment of phenol-contaminated soil by potassium ferrate. Variations in pH value can accurately reflect the state and reaction status of the entire treatment process. Therefore, the pH value could be an important variable for optimizing the reaction conditions and achieving the automatic control of the process. About 99.89% of phenol was removed after 10 min of the pH-contxolled reaction at a rotational speed of 40-70 r/min, with the initial phenol concentration equating to 10.0 g/kg and the total water consumption reaching 2.72 L （at a soil/water ratio of 1：0.68）. The test results could provide a basis for practical application of automatic reaction control by pH value.

家庭洗涤脱落的合成纤维是水环境中纤维微塑料的主要来源之一。纤维微塑料结构稳定、不易分解,会长期存在于水体、土壤和动物体内,对环境造成破坏。为了更好地了解织物纤维微塑料释放机制,从织物性能和洗涤参数两方面归纳织物纤维微塑料释放的影响因素,并从洗涤机械力和织物性能变化角度介绍了织物纤维微塑料释放机制。最后总结出:不同洗涤条件引起的洗涤机械力和织物性能的变化是影响织物纤维微塑料释放量变化的主要因素之一,洗涤机械力对纤维微塑料的释放起到一定的促进作用,从洗涤机械力角度寻找织物纤维微塑料污染问题的缓解措施对减少织物纤维微塑料释放具有重要意义。

The research aimed to develop and validate an ion chromatography method for the simultaneous analysis of Cr(Ⅲ) and Cr(Ⅵ)from pumpkin. A new analytical method based on ion chromatography techniques was developed by the Cr(Ⅲ) pre-column derivatization and Cr(Ⅵ) post-column derivatization. The ion chromatography condition was optimized and the detection sensitivity was improved. Cr(Ⅲ) and Cr(Ⅵ) were determined by 365 and 530 nm,respectively. The temperature of water bath,the heating time for pre-column derivatization,and the flow rate of post-column derivative liquid were screened on the basis of single factor experiment,the effects of various factors were determined by the method of L16( 43) orthogonal experiment design. Considering the results of orthogonal experiments and the variation tendency of peak area under different factors,the optimum derivatization conditions were chose as follows: the flow rate of post-column derivative liquid is0. 5 m L/min,the temperature of water bath for pre-column derivatization is 100 ℃ and the heating time is 5 min. The conditions were optimized by means of orthogonal experiments under the p H of leacheate ranged from 6. 5 to 6. 8 and the I-concentration of 5 mmol/L. Under optimized derivatization conditions,the detection limits for Cr(Ⅲ) and Cr(Ⅵ) were 0. 17 and 0. 019 mg,respectively. And the average recoveries of Cr(Ⅲ) in pumpkin were in the range of 82%-85%. Results indicated that pumpkin does not contain Cr(Ⅵ) according to this ion chromatography method of simultaneously determination for Cr(Ⅲ) and Cr(Ⅵ).

Glucosinolate composition and content were evaluated in flowers and leaves of 12 different broccoli varieties. The results indicated that there were 9 glucosinolates in broccoli,namely Glucoiberin(IBE); Progoitrin(PRO);Sinigrin(SIN);Glucoraphanin(RAA);Gluconapin(NAP);4-Hydroxyglucobrassicin(4OH);Glucobrassicin(GBC);4-Methoxyglucobrassicin(4ME);Neoglucobrassicin(NEO).Total glucosinolate content in flowers was 1-5 times higher than in leaves. The predominant glucosinolate in broccoli was glucoraphanin.

纤维微塑料是微塑料的主要构成形式,对环境中的其他污染物具有较强的吸附能力,对生物和人体存在潜在的毒害作用。本文为了研究减少纤维微塑料的释放,认为有必要对其释放因素和机制进行探讨。然而,大多数研究是针对纺织产品洗涤过程中纤维微塑料释放的研究,对于纺织品全生命周期其他过程中纤维微塑料的脱落未进行深入研究。本文综述了纤维微塑料的基本概念及主要来源,总结了纺织产品生产、使用、废弃过程中纤维微塑料的释放因素,整理归纳了现阶段针对减少纤维微塑料污染问题的方法策略。结果表明:纺织产品全生命周期的各个阶段释放的纤维微塑料量主要受机械作用影响,其中纺织品护理过程是形成纤维微塑料最多的阶段,对洗涤/烘干参数或洗衣机结构优化,在洗衣机、烘干机上安装高效率的过滤器,可有效降低纤维微塑料向环境中的释放,对缓解纤维微塑料污染具有重要意义。
