The extensive use of crystal violet (CV) dyes may cause water pollution. A highly porous and functionalized activated carbon can be used for adsorption CV dyes. Activated was prepared from oil palm fronds through microwave-assisted pyrolysis activation with phosphoric acid (H3PO4) removal dye wastewater. physico-chemical characteristics (OPFAC) employed by Brunauer-Emmett-Teller (BET) surface area analysis, Fourier transform infrared (FT-IR) Scanning Electron Methodology-Energy Dispersive...
The potential of Pleurotus ostreatus spent mushroom compost (PSMC) as a green biosorbent for nickel (II) biosorption was investigated in this study. A novel approach using the half-saturation concentration to rapidly determine uptake, kinetics and mechanism employed together with cost per unit uptake analysis biosorbent. Fifty cent obtained at constant 0.7 g concentration, initial pH range 4–8, 10 min contact time, 50 mL mg/L concentration. experimental data were well fitted Langmuir...
Cat manure (CM) possesses high level of nutrients for growing food crop. However, animal may contain toxic elements that contaminate Spent coffee ground (SCG) be used to reduce mobility heavy metals and crop uptake. In this study, SCG was composted with CM 31 days produce a co-compost (SCG-CM) spinach (Spinacia oleracea). The growth rate assessed until its maturity, the metal uptake shoot determined thereafter using inductively coupled plasma-optical emission spectroscopy (ICP-OES). effect...
Changes in soil nutrients have been applied legal investigations of the time death or to locate a clandestine grave. However, research on forensic chemistry under tropical climate conditions Malaysia is at its infancy, with few data available for investigations. This study aims changes (i.e. ammonia, phosphate and nitrate) as well pH electrical conductivity (EC), associated stages decomposition rat carcasses (n = 3) controlled conditions. The results showed differences between control...
Pleurotus spent mushroom compost is usually discarded as agricultural waste. This study investigated the biosorption characteristic of copper by compost. Parameters including biosorbent concentration, initial pH, contact time, (II) concentration and temperatures were examined in batch mode. Half saturation constant was obtained at 1.4 %(w/v) unadjusted pH 5.5, 10 minutes time 50 mg/L solution. Copper process well fitted to Langmuir isotherm pseudo second order kinetic model. Generally, not a...
Cocoa pod husk (CPH) was pyrolyzed at 500°C to produce biochar (CPHB) for sorption of lead (Pb) from aqueous system. Chemical characterization CPHB conducted using Fourier transform infrared (FTIR) spectroscopy, Boehm titration and X-ray fluorescence (XRF) spectroscopy. Sorption parameters (i.e., sorbent dosage, pH, contact time, Pb concentration) were optimized. Elemental compositions are C (66% w/w), O (19% N (2% w/w). The ash consists calcium oxide (CaO) (4.6% w/w) potassium (K2O) (4.2%...
Oil palm plantations produce kernel shell (PKS) that can be converted into biochar for environment-friendly soil remediation and water treatment. Oxidation with hydrogen peroxide (H2O2) may enhance surface characteristics the quality of low-rank PKS as a sorbent environmental decontamination. This study aims to determine effect oxidation on (i.e., specific area, charge, chemical properties) biochar, compared activated carbon. The area oxidised was similar indicating did not remove pore...
Molecules with pyranobenzophenone moiety are widely distributed in nature. They have a range of biological and pharmacological properties. Among these, clusiacitran A (1) citran nucleus was isolated as an optically inactive racemate along B (2) from extract the fruits Clusia multiflora (Figure 1). Recently, also Gaucinia schombrugkiana Pierre, which collected Songkla area southern Thailand fluorinated clusiacitrans (3) (4). This plant is used treatment coughs diabetes well for improving...
Biosorption is fast becoming an attractive method for heavy metal contaminated wastewater treatment. This paper investigates the uptake capacity and removal of lead (II) by Pleurotus ostreatus biomass under influence concentration, initial pH containing solution, contact time Pb(II) concentration as to ascertain usability biosorbent removal. Optimum were found be at 0.5g biosorbent, with percentage 88% 4.3 ± 0.1 mg/g 60 min. Possible range application this from 4 6 showed high (II). Uptake...

Biochar has an alkaline and porous structure that could be a potential material for recycling phosphorous (P) from urine. Sawdust (SD) was pyrolyzed to produce sawdust biochar (SDB), then impregnated with magnesium (Mg) Mg-impregnated (SDBM). Artificial human urine (AHU) solution used batch sorption study, various parameters (i.e., sorbent/solution ratio, pH of AHU, initial total P concentration AHU) were optimized. The measured using inductively coupled plasma-optical emission spectroscopy...
Leaching of lead (Pb) from the shooting range soil may contaminate water resource if rain pH decreases and has a low cation exchange capacity (CEC).Over exposure Pb cause brain injury death.In this study, leaching was simulated with column test using artificial at 4 7.
