The quantity of biogas residues is continually increasing and causing a great threat to the environmental protection sustainable development bio-natural gas engineering. Thus, four (sewage sludge, SR; spent mushroom compost, MR; wheat straw, STR; distillers’ grains, DL) were collected prepare biochars at different temperatures (300 °C, 500 700 °C) in this study. functional groups, crystal struc...

The presence of heavy metals in the environment as a consequence human activity is an issue that has caught attention researchers to find wastewater treatment solutions, such adsorption. In this work, hydrochars and activated carbon microspheres are prepared from tangerine peels precursor FeCl3 activating structure-directing agent hydrothermal carbonization, allowing obtain hydrochar ranging 50...

Micro- to mesoporous iron(iii) trimesate MIL-100(Fe) is a MOF of high interest for numerous applications. With regard to large-scale synthesis, e.g., by continuous flow or the in situ deposition of coatings, a replacement for the conventional, hydrothermal low-yield fluoride-containing synthesis is desirable. In this contribution, we present a method to synthesize crystalline fluoride-free MIL-...

Lead is the main toxic factor in jarosite residue. It important to study release behavior of lead from simulated lead-bearing (SLBJ) for predicting stability residue and its secondary pollution environment. To identify technical issues limitations associated with safe disposal, a comprehensive analysis chemical, structural, morphological characteristics SLBJ was conducted using various detectio...

This chapter presents an overview of the literature on the effect of phosphorus modification of ordered mesoporous silica (OMS) such as MCM-41, HMS, SBA-15, and SBA-16 to be used as supports for hydrotreating catalysts based on transition metal sulfides (TMS). The influence of the support modification with variable quantities of phosphorus on the performance for hydrodesulfurization (HDS) and h...

Sequential extractions, metal uptake by Taraxacum officinale, Ruby’s physiologically based extraction test (PBET) and toxicity characteristic leaching procedure (TCLP), were used to assess the risk of Pb and Zn in contaminated soils, and to determine relationships among soil characteristics, heavy metals soil fractionation, bioavailability and leachability. Regression analysis using linear and ...

Jarosite released from zinc metal extraction process is hazardous in nature and its world wide disposal has become a major environmental concern. In this study, an attempt has been made to immobilise and recycle the jarosite released from Hindustan Zinc Limited, India, using CCRs, so called fly ash, and clay soil. Results revealed that the particle size of jarosite was finer than that of CCRs a...

Lumpur yang dihasilkan dari instalasi pengolahan air minum di Indonesia masih belum dimanfaatkan dengan baik dan menjadi permasalahan bagi lingkungan. Salah satu alternatif dapat diterapkan yaitu memanfaatkan lumpur tersebut sebagai bahan baku paving block. Penelitian ini bertujuan untuk menganalisa perbandingan limbah hasil uji daya serap air, kekuatan Toxicity Characteristic Leaching Procedur...

Leaching of arsenic from brick manufactured from arsenic and iron sludge has been investigated in this study. TCLP result shows that leached metal concentrations are far below the regulated TCLP limits and the quantities of metal leached from sludge are less than those from dried sludge. The results of Atterberg limits tests of moulded sludge-clay mixtures indicated that both plastic index and ...
