multiwavelength pectrophotometric determination of stability constants of 4-(2– thiazolylazo) resorcinol (tar) with la3+, y3+ and th4+ in organic-water mixed solvents by chemometrics method & simultaneous spectrophotometric determination of lead, copper and nickel using xylenol orange by partial least squares calibration method
تشکیل کمپلکس های tarبا یون های لانتانیم, ایتریم و توریم در دمای 25 درجه، قدرت یونی ثابت 0.1 مولار و در ph ثابت در مخلوط حلال های اتانول – آب و استونیتریل – آب با استفاده از روش های اسپکتروفوتومتری مورد بحث و بررسی قرار گرفت. داده های اسپکتروفوتومتری با استفاده از نرم افزار squad پردازش شدند تا ثابت های تشکیل کمپلکس اندیکاتور – فلز را محاسبه کند. نتایج نشان می دهد که درصد حلال آلی در مخلوط حلال ...
15 صفحه اولTrace determination and separation of tin (II) by floatation-spectrophotometric using kalmagyte and CTAB
ABSTRACTA novel floatation-spectrophotometric extraction method was developed for the recovery of tin (II) from aqueous samples prior to determination by UV spectrophotometric detection. The method is based on the formation of a complex between tin (II) and kalmagyte in pH=8. The complex is floated in the interface of n-hexane and aqueous phases. After removing the aqueous phase, the floated pa...
متن کاملDetermination of Copper (II) and Palladium (II) by Polarographic Methods
Schiff base 2–Hydroxy–5–methoxy Benzaldehyde – Tris [HMBT] Ligand is a new chromogenic reagent have not been used so far for the determination of copper and palladium in trace quantities. Effect of p H on wave height for COPPER[HMBT] PALLADIUM –[HMBT] systems have been studied at p H 7-8.5 and 8.5-11.5 for Copper and Palladium respectively in 0.1 m molar NaNo3 and 0.002 % Triton –x–100 which in...
متن کاملSimultaneous spectrophotometric determination of lead, copper and nickel using xylenol orange by partial least squares
A partial least squares (PLS) calibration model was developed for the simultaneous spectrophotometricdetermination of Pb (ΙΙ), Cu (ΙΙ) and Ni (ΙΙ) using xylenol orange as a chromogenic reagent. The parameterscontrolling behavior of the system were investigated and optimum conditions were selected. The calibrationgraphs were linear in the ranges of 0.0–9.091, 0.0–2.719 and 0.0–2.381 ppm for lead...
