Dual determination of nitrite and iron by a single greener sequential injection spectrophotometric system employing a simple single aqueous extract from Areca catechu Linn. serving as a natural reagent

Abstract

Dual determination of nitrite and iron was proposed by using a single greener sequential injection (SI) spectrophotometric system employing a simple single aqueous extract from Areca catechu Linn.

Ultrasound-Assisted One-Pot Cloud Point Extraction for Iron Determination Using Natural Chelating Ligands from Dipterocarpus intricatus Dyer Fruit

“…In molecular spectroscopic fields especially UV-Visible spectrophotometry, many publications have reported natural plant extractions as alternatives to commercially available reagents for the development of environmentally-friendly analytical methods, such as pumpkin for benzoyl peroxide assay [ 12 ], turmeric ( Curcuma longa L.) for acetic acid assay [ 13 ], Indian mulberry root [ 14 ], heartwood of sappan wood [ 15 ] and Indian almond leaves [ 16 ] for aluminum assay, slippery elm ( Ulmus rubra ) leaf to determine trace amounts of molybdenum(VI) [ 17 ], and Oriental plane tree ( Platanus orientalis ) for the determination of zirconium [ 18 ]. Natural reagents have been developed as green analytical methods to quantify iron such as Indian gooseberry [ 19 ], guava leaves [ 20 ], green tea [ 21 ], betel nut [ 22 , 23 ], lead tree [ 24 ], and Smilax china root [ 25 ].…”
