Titolo: Spectrophotometric determination of boron in water effluents and fertilizers by sequential injection analysis Autore: van Staden, JF; van der Merwe, TA; Indirizzi: Univ Pretoria, Dept Chem, ZA-0002 Pretoria, South Africa Univ Pretoria Pretoria South Africa ZA-0002 -0002 Pretoria, South Africa Titolo Testata: SOUTH AFRICAN JOURNAL OF CHEMISTRY-SUID-AFRIKAANSE TYDSKRIF VIR CHEMIE fascicolo: 2, volume: 53, anno: 2000, pagine: 77 - 85 SICI: 0379-4350(200009)53:2<77:SDOBIW>2.0.ZU;2-7 Fonte: ISI Lingua: ENG Soggetto: SOILS; Tipo documento: Article Natura: Periodico Settore Disciplinare: Physical, Chemical & Earth Sciences Citazioni: 27 Recensione: Indirizzi per estratti: Indirizzo: van Staden, JF Univ Pretoria, Dept Chem, ZA-0002 Pretoria, South Africa Univ Pretoria Pretoria South Africa ZA-0002 South Africa Citazione: J.F. van Staden e T.A. van der Merwe, "Spectrophotometric determination of boron in water effluents and fertilizers by sequential injection analysis", S AFR J C-S, 53(2), 2000, pp. 77-85 -------------------------------------------------------------------------------- Abstract A sequential injection system for the on-line monitoring of boron in watereffluents and fertilizer process streams is proposed. Azomethine-H, a condenisation product of saljcylaldehyde and H acid (8-amino-1-naphtol-3,6-disulphonic acid) is used as the chromogenic reagent. In solution the chromogenic reagent exists as two constituents. When boron is added to the solution. Azomethine H is formed and measured at 420 nm. The proposed system is fully computerised and is able to monitor boron at a rate of 28 samples per hour with a relative standard deviation less than 1.6%. The calibration curve is linear up to 100 mg l(-1). The system has a detection limit of 0.62 mg l(-1). |
