“…To date, considerable works have been devoted by researchers to processing these types of catalysts. [1][2][3][4][5][6] The investigations carried out by our research group [5][6][7][8] include the selective extraction of titanium followed by quantitative leaching of tungsten and vanadium carried out through soda roasting, followed by alkali dissolution, generating a leach solution with about $7000 mg L À1 tungsten and $700 mg L À1 vanadium. [5][6][7][8] Hence, the real issue for this leach solution is to extract and separate out the enriched content of either of these metals from the above leached solution.…”

“…The main sources of anthropogenic vanadium are the combustion of fossil fuels (especially oil), mining, processing of ores, production of steel alloys, glass, ceramics, rubber, redox batteries and dyes, application in catalysts for large-scale processes, fertilizing and recycling of domestic waste. 3,9,11,12 At present, vanadi-um has the highest anthropogenic enrichment factor of all trace elements in the atmosphere; it ranks fourth in this factor for global rivers (after antimony, cadmium and nickel). 13 Many organic reagents have been applied for vanadium preconcentration and determination.…”

Liquid-liquid extraction-chromogenic systems for vanadium(V) based on xylometazoline hydrochloride (XMZ) and azo derivatives of resorcinol (ADRs) were studied. The following ADRs were used: 4-(2-thiazolylazo)resorcinol (TAR), 5-methyl-4-(2-thiazolylazo)resorcinol (MTAR), and 6-hexyl-4-(2-thiazolylazo)resorcinol (HTAR). Concentration of the reagents, pH of the aqueous medium and shaking time were subjects of optimization experiments. The chloroform-extracted ternary complexes were of composition 1:1:1. The molar absorptivity coefficients (ε λ), absorption maxima (λ), constants of extraction (Log K), and fractions extracted (E%) were found to be ε 553 = 2.50 × 10 4 dm 3 mol-1 cm-1 , Log K = 3.5, and E = 96% (ADR = TAR); ε 550 = 1.88 × 10 4 dm 3 mol-1 cm-1 , Log K = 3.4, and E = 98% (ADR = MTAR); and ε 554 = 2.62 × 10 4 dm 3 mol-1 cm-1 , Log K = 5.0, and E = 99.5% (ADR = HTAR). The Sandell's sensitivities and Beer's law limits were determined as well.

“…Beberapa tahun terakhir, berbagai proses hidrometalurgi dan pirometalurgi dikembangkan untuk memperoleh kembali logam-logam yang memiliki nilai ekonomis seperti vanadium dari katalis vanadium bekas (Nguyen & Lee, 2014;Erust, et al, 2016;Nagib & Abdel Hameed, 2017;da Cruz Deniz, Valt, Kaminari, de Santana Ponte, & de Araújo Ponte, 2018;Kim, Moon, Choi, Lee, & Jyothi, 2018). Proses-proses tersebut umumnya meliputi pembakaran, ekstraksi padat-cair dengan larutan asam basa, peleburan, klorinasi anhidrat, bioleaching, dan pembakaran garam diikuti dengan pencucian dengan air.…”

Katalis vanadium bekas diperkirakan akan menjadi salah satu sumber utama persediaan vanadium di masa mendatang. Hasil analisis vanadium dalam katalis vanadium bekas menunjukkan bahwa kadar V2O5 nyamasih cukup banyak untuk diambil dan diolah kembali. Dalam penelitian ini, suatu prosedur telah dikembangkan untuk mengesktraksi vanadium dari katalis vanadium bekas berdasarkan prosedur yang dikembangkan oleh peneliti terdahulu. Katalis vanadium bekas uji coba prosedur menunjukkan bahwa metode gabungan ekstraksi vanadium dari katalis vanadium bekas menggunakan pelarut basa Na2CO3 dan H2O2 pada umpan (tahap ekstraksi pertama) dan NaOH (tahap ekstraksi kedua) yang diikuti dengan netralisasi filtrat dengan asam H2SO4 merupakan prosedur terbaik. Lebih lanjut, terdapat tiga variabel yang sangat berpengaruh dalam pengambilan kembali vanadium dari katalis vanadium bekas, yang ditandai dengan nilai probability of being active di atas 50%. Ketiga variabel tersebut adalah temperatur pengadukan pada tahap ekstraksi II, penambahan larutan H2O2 di umpan dan waktu pengadukan pada tahap ekstraksi I dengan nilai probability of being active secara berturut-turut sebesar 100%, 86%, dan 56%. Untuk mendapatkan perolehan vanadium yang lebih tinggi perlu diadakan penelitian lanjutan yang mengoptimumkan variabel-variabel tersebut.
