In order to investigate the effect of growth media and nutrition method on the growth of Bellis perennis L. and nutrients uptake, a factorial experiment was conducted with two factors: growth media (municipal waste compost, Azolla compost, tea wastes compost) and nutrition method (without fertilizer, soil application, foliar spray) in comparison to the control medium (60% soil + 20% manure + 10...
Background and purpose: The presence of phenol and its derivatives in water and wastewater are of major concern because of their toxicity and threat to human life and environment. The aim of this study was determination of the modified lemna minor and azolla in phenol adsorption. Materials and methods: In this emperical-lab study, the washed lemna minor and azolla was used as adsorbents. The e...
فلزات سنگین از سمی ترین آلایندها در محیط زیست می باشند که به دلیل عدم تجزیه پذیری، اثرات آلایندگی نظیر مسمومیت، بیماری، موتاسیون، ورود به زنجیره غذایی و ..... را به بار می آورند. فلزات سنگین با روش های ترسیب شیمیایی، الکترولیز، کاربرد مواد منعقد کننده، سیستم های تبادل یونی، روش های غشایی، جذب سطحی، تبخیر و روش های بیولوژیک، حذف شده یا کاهش می یابند . در حال حاضرحذف آلاینده ها به خصوص فلزات سنگی...
Biodiversity is threatened by humankind’s continuing usurpation of our planet’s physical space and resources, and the associated damage to the landscape and atmosphere. Food production is widely acknowledged to be the most important human activity that needs to be addressed in order to mitigate the current biodiversity and environmental crises. In this contribution we feature obscure plants cal...
Background and purpose: The textile dyes are considered as important pollutants due to the toxicity on human and environment. Therefore, the dye removal from industrial effluents is necessary. This study evaluates the ability of Azolla for the adsorption of acid black 1 (AB1) dye from aqueous solution. Materials and Methods: This was an experimental-laboratory study. The Azolla biomass was sun ...
Environmental sustainability is an integral aspect of living a better life, which will continue to be globally highlighted in the future. Sustainable Development Goals (SDGs) are crucial most research areas improve natural resources that ensure long-term viability environment. The rising population may lead increased pollution due extensive anthropogenic activities. Natural being increasingly e...
Objective: The present study was designed for isolation of bioactive polyphenolic compounds from methanol extract of Azolla microphylla and their subsequent characterization. Methods: The flavonoid compounds were isolated and characterized by using thin layer chromatography (TLC), purified by preparative thin layer chromatography (PTLC) and were identified using High performance chromatography ...
