Quantitative analysis of silicon tetrachloride, carbon disulfide, and dichloroethane concentrations to obtain vapor-liquid equilibrium data the SiCl4-CS2 SiCl4-C2H4Cl2 binary systems was established by Raman spectroscopy. The cheap glass sampling pipe used as a carrier for spectroscopy measurements. peak height internal standard remove interference factors such diameter, temperature, laser power, other effects from instrument. ratio between characteristic analyte that proportional...
Iron ore tailing with phosphorus (IOTP), as industrial solid waste was used to remove Pb(II) ion from aqueous solution.Factors influencing the adsorption process were analyzed, and related mechanism discussed.The results indicate that of onto IOTP is strongly dependent pH value solution.An optimum capability achieved at = 6.0.Complexation acts vital for Pb (II) removal when varies 1.5 7.0.While chemical precipitation plays an important role rising beyond 7.0.Kinetic studies show by rapid...
Raman spectroscopy with an internal standard and peak height ratio was applied for the quantitative analysis of dichloromethane titanium tetrachloride.
Highly crystalline CdS with an S defect and a Cl dopant was synthesized through low-temperature calcination within semi-liquid-state complex chloride molten salts.
Because their oxidation products are more prone to oxidation, converting inert C-H bonds in alkanes into high value-added product KA oil with selectivity is still a significant obstacle. In this study, flower-like microspheres of MoO3-x, featuring aligned nanosheets and oxygen vacancies, were combined nitrogen doped carbon dots (NCDs) fabricate S-scheme heterojunctions MoO3-x-NCDs for boosting the photocatalytic efficiency oxidizing cyclohexane. vacancies-triggered localized surface plasmon...
Generally, hydrometallurgy process is adopted in factory to recover valuable metal from anode materials lithium ion battery. The mother liquor generated the precipitation of carbonate this often managed by evaporative crystallization which high energy-consuming and expensive. methodology employed research involves pretreatment bipolar membrane electrodialysis partition salts within into acids bases, thereby achieving cost savings. findings reveal that a significant 76.5 % reduction COD...
This work studied the effect of B2O3 (analytical reagent) on parameters a sintering pot test, as well metallurgical properties and microstructure sinter samples, to determine feasibility applying solid waste containing in vanadium–titanium sintering. The results show that along with addition, mechanical strength first increases then decreases; maximum was found upon addition 3.0% B2O3. low-temperature reduction pulverization rate were also improved, while start end temperatures softening...
In general, the saponification effluent result from rare earth metallurgical process is often characterized by high chemical oxygen demand (COD) and phosphorus salt concentrations.This paper presents a method for simultaneously removing COD via Fenton oxidation precipitation.A series of experiments were conducted to enhance removal which contained 924 mg/L 15.5 phosphorus.Experimental results showed that pH solution, reaction time, H 2 O Fe 2+ concentrations exert significant effects on...
The extraction of nickel from ferromolybdenum leach residues by sulphation roasting, water leaching and iron removal subsequent solutions was studied. Sulphation roasting promote the reaction between sulphuric acid residue decrease silicon dissolution. Over 90% Ni leached. Ferric ions in solution could be effectively removed as jarosite ferric hydroxide. recovery reached 88·3% under with quality 1472 kg t−1 at 280°C for 4 h followed addition 0·5 g NaClO3, 6 Na2SO4 10 CaO/100 mL 95°C 2·5 h,...
Solar energy in nature is irregular, so photovoltaic (PV) power performance intermittent, and highly dependent on solar radiation, temperature other meteorological parameters. Accurately predicting to ensure the economic operation of micro-grids (MG) smart grids an important challenge improve large-scale application PV traditional systems. In this paper, a hybrid machine learning algorithm proposed predict accurately, Persistence Extreme Learning Machine(P-ELM) used train system. The input...
