The purpose of this study was to evaluate the effect of phytoremediation on reduction of phosphate, nitrate, chemical oxygen demand (COD) and biochemical oxygen demand (BOD) of Ahwaz wastewater during 90 days. A completely randomized design with 4 treatments and 3 replications was used for this experiment. The plants of Typha Latifolica and seven grasses (Polygonum aviculare) were selected acco...
This paper discusses the influence and content of Typha Australis fibers on thermal mechanical properties clay composites. The objective is to find a better combination length percentage fibers. will allow have good compromise between properties. results found at end this study are conclusive. Indeed, increase percentages fibres improve but values compressive resistances decrease.
Palynomorphs extracted from the mud coffins and plant remains preserved at the archaeological site of Xiaohe Cemetery (Cal. 3980 to 3540 years BP) in Lop Nur Desert of Xinjiang, China were investigated for the reconstruction of the ancient environments at the site. The results demonstrate that the Xiaohe People lived at a well-developed oasis, which was surrounded by extensive desert. The veget...
The aim of this study is to investigate the adaptation two species cattail Typha australis Schum. and Thonn. laxmannii Lepech. based on analysis morphological anatomical features their vegetative generative organs soil pollution with potentially toxic elements (PTE) in riparian zones sea edge Don River delta (Southern Russia). Both are able accumulate high concentrations Ni, Zn, Cd, Pb can be u...
Biomass and contaminant accumulation and partitioning in plants determine the harvest stage for optimum contaminant uptake during phytoremediation of municipal biosolids. This wetland microcosm bioassay characterized accumulation and partitioning of biomass, nutrients (N and P), and trace elements (Zn, Cu, Cr, and Cd) in cattail (Typha latifolia L.) in a growth room. Four cattail seedlings were...
the modified surface of typha latifolia l. root (mstl), as an alternative economical adsorbent, wasused for the removal of ni (ii) and cd(ii) ions from aqueous solutions. the effect of initial ph, initialconcentration of metal ion, and contact time was investigated in a batch system at room temperature.the kinetics data could be fitted well by pseudo-second-order model with correlation coeffici...
تالاب بینالمللی فریدونکنار در جنوب شرقی مناطق کم ارتفاع دریای خزر قرار دارد و با وسعتی معادل 5427 هکتار در محدوده جغرافیایی 52 درجه و 31 دقیقه طول شرقی و 36 درجه و 45 دقیقه عرض شمالی واقعشده است. نمونههای گیاهی از 6 ایستگاه جمعآوری و به طریق علمی خشک و پرس و با کمک کلیدهای تخصصی شناسایی و شکل زیستی و کوروتیپ آنها مشخص گردید. در این مطالعه که در سالهای 91 تا 92 و در چهارفصل سال ان...
