This study assessed the applicability of Fe-impregnated biochar derived from cattle manure (Fe-CMB) as an adsorbent for removing Sb(V) aqueous solutions and investigated adsorption mechanism. Fe-CMB was mainly composed C, O, Cl, Fe, Ca, P, onto identified using energy dispersive spectrometer Fourier transform infrared spectroscopy. reached equilibrium within 6 h, data a function time were well ...

Aluminum-impregnated food waste was selected as a filter medium for removing As(III) from aqueous solutions. The modification of and its carbonization conditions were optimized using the Box–Behnken model in response surface methodology. Pyrolysis temperature Al content significantly influenced adsorption capacity aluminum-modified biochar (Al-FWB), but pyrolysis time insignificant. Several fac...

Objective: To determine water quality in the central zone of Texcoco aquifer, Mexico, for human use and consumption agricultural use. Methodology: The physical, chemical, biological indicators from 16 wells urban areas aquifer were determined. sampling was carried out, based on parameters definition per established current official Mexican standards. Results: According to physical concentration...

The use of anaerobic hydrolytic fermentation to develop more available carbon sources from domestic sewage influent particulate organic matter (POM) has received increasing attention. However, the slow hydrolysis rate POM limits application this technology. This study aimed improve source release efficiency by pH adjustment and reveal mechanism. Results showed that adjusting initial 3, 9, 11 en...

The main of this study is to estimate the maximum density fish in growing basins rainbow trout (Oncorhynkiss Mykiss) species by mathematical equations, which will be used introduce environmental concerns. Indeed, these equations make it possible fed extruded feed B and two elaborated exruded feeds (F1 F2) achieve an optimal production without harming environment. Note that elements (PO43-, NH4 ...

Solok rice is an important agricultural commodity that contributes significantly to the economic prosperity of West Sumatra region. As indigenous knowledge from Sumatra, development and preservation can stimulate a nationwide increase in production. The cumulative effects entire sequence activities comprising production will impact environmental quality due increased output. Therefore, Life Cyc...

The present work features some simple methods of preparing pure hydroxyapatite nanoparticles (nano-HAp), a useful biomaterial, via various wet chemical and using biogenic sources such as eggshells animal bone. nano-HAp hence prepared was subsequently characterized by FTIR spectroscopy XRD technique. spectra confirmed the presence PO43- OH- ions major functional groups in material, with addition...

The present study aimed to identify the abilities of δ-aminolevulinic acid (ALA) producing purple non-sulfur bacteria (PNSB), Luteovulum sphaeroides W22 and W47, reduce Na+ concentration, ameliorate soil fertility, nutrients uptake, growth yield rice on salt-contaminated soil. A two-factor experiment was conducted following a completely randomized block design. factors were frequency applying s...

This study analyzes multiyear data recorded by 21 stations along an elevation gradient (0–1045 m a.s.l.) in the Luquillo Mountains on rainfall and rainwater chemistry. The total ionic concentration volume exhibited inverse exponential relationship, with correlation coefficients ranging from –0.66 to –0.90. Furthermore, tended increase elevation, although a few stations, owing their geographical...
