The non-competitive and competitive adsorption/desorption of agrochemicals into soil plays an important role in the fate and behaviour of contaminants in the environment. Non-competitive and competitive adsorption/desorption experiments of imidacloprid and KNO3 into alluvial soil and sandy soil were...

This study presents the results of the biogas purification test using the fixed-bed column method. As an adsorbent, natural zeolite from the Lombok island Indonesia was used. Zeolite is used for the purpose of purifying biogas produced from the anaerobic digestion (AD) process. To enhance the...

Under the greenhouse scale, nano zero valent iron (nZVI) have been evaluated evaluated by formulation with carboxymethyl cellulose (CMC-nZVI), chitosan (Ch-nZVI), biochar (BC-nZVI), and smectite (SC-nZVI) at rates of 0 and 0.5 and 1% (w/w). The properties of manufactured compounds and their impact...

Biowalls are a new phenomenon in interior urban areas, which has proven to contribute positively to sensory comfort. But people use biowalls in different dimensions. Based on field facts, determining the biowall dimensions for human sensory comfort has not emphasized clear principles. The research...

Cadmium (Cd) is a highly hazardous metal known for its easy absorption and accumulation in plants, particularly in edible vegetable oils. Sunflower (Helianthus annuus L.) holds global significance as an oil crop. This study aims to assess the potential of zinc-solubilizing bacterial strains in...

Most of the tungsten tailings (TTs) are filled in the open. As a result, the phenomenon that acid rain influences the engineering geological characteristics of tungsten tailings is impossible to avoid, especially in southern China, where acid rain occurs frequently. This work studied the...
