The preliminary assessment of the properties of alginate immobilized aquatic weed Myriophyllum spicatum beads–MsAlg in a multi-element system of nine Serbian lakes water samples was done. Herein, the results obtained in the biosorption experiment with MsAlg contents of twenty-two elements analysed by inductively coupled plasma–optical emission spectrometry, biosorption capacity, element removal efficiency, total hardness (TH) and quality index of water (WQI) are presented. Scanning electron microscopy with energy dispersive X-ray spectroscopy was used for the characterization of M. spicatum and its beads. The study showed that aluminium, magnesium and strontium were adsorbed by MsAlg in the water samples from all examined lakes; barium and iron in the water samples from six lakes. The overall average efficiency of MsAlg in biosorption of elements was in the following order: Al > Ba > Sr > Fe > Mg (58.6, 51.7, 48.2, 23.9 and 17.7%, respectively). The increase of TH and WQI values after the biosorption was noticed in all studied lake water samples. The most significant correlations for pH were regarding the contents of B, Mg and Ca, whereas WQI was highly correlated to the contents of B and Mg, and pH. The complexity of the obtained data was explained by Cluster Analysis and Principal Component Analysis, which showed good discrimination capabilities between the water samples taken from different locations. Considering that the invasive M. spicatum is natural, widespread and that its immobilization is cheap and eco-friendly, presented findings could be helpful in further assessment of MsAlg beads for its potential use as biofilter.

应用多准则分析对湖水中水藻酸盐固定的Myriophyllum spicatum的性质进行初步评估

初步评估了藻酸盐固定的水生杂草Myriophyllum spicatum珠–MsAlg在9个塞尔维亚湖水样的多元素系统中的性质。本文介绍了在生物吸附实验中通过电感耦合等离子体发射光谱法分析的22种元素的MsAlg含量,生物吸附能力,元素去除效率,总硬度(TH)和水质指数(WQI)的结果。扫描电子显微镜与能量色散X射线光谱法被用于表征辣根霉。和它的珠子。研究表明,铝,镁和锶被MsAlg吸附在所有检查过的湖泊的水样中。六个湖泊的水样中的钡和铁。MsAlg对元素的生物吸附的总体平均效率按以下顺序排列:Al> Ba> Sr> Fe> Mg(分别为58.6、51.7、48.2、23.9和17.7%)。在所有研究的湖水样品中都发现了生物吸附后TH和WQI值的增加。pH的最显着相关与B,Mg和Ca的含量有关,而WQI与B,Mg和pH的含量高度相关。聚类分析和主成分分析解释了所获得数据的复杂性,这表明从不同位置采集的水样之间具有良好的区分能力。狐尾藻是很自然的,普遍的,并且其固定是廉价和环保,呈现结果可能是在其作为生物滤池的潜在用途的MsAlg珠进一步评估有帮助。
