Colorimetric Determination of Boron Using Carmine

Abstract

VOLUME 2 2, NO. 4, APRIL 1950 567 cupric ions. Methods were also found whereby these metals could be determined in the presence of the other ions. A future pubiica-(ion will discuss the industrial applications of this reagent.

Comparative Study of Boron Accumulation in Flag Leaf, Spike and Grain of Wheat (Triticum aestivum L.) Grown under Heat Stress

“…The plant samples were washed with 0.2% liquid detergent (The liquid detergent removes waxy coating of the leaf surface and any soil particle) solution, than with 0.1N HCl solution (0.1N HCl removes metallic contaminants) and finally with deionized water (Deionized water washes the previous two solutions). After that the extra moisture was wiped out, the sample was placed in new paper bags and dried in an oven at 70 0 C. Plant samples were digested following the methods given by Hatcher and Wilcox (1950). 0.5g oven dried sample was digested in diacid mixture (HNO3:HClO4, 10:4) on a rectangular hot plate.…”

N–p–k Fertilizer Effects on Yield, Composition and Residues of Lettuce, Celery, Carrot and Onion Grown on an Organic Soil in Quebec

“…Boron was determined after dry-ashing according to the procedure described by Hatcher and Wilcox (1950). After wet-ashing with a mixture of nitric, sulfuric and perchloric acids, total P in plant tissue was determined by the phospho-molybdovanadate procedure (Kitson and Mellon 1959) For personal use only.…”

The effect of boron fertilization on spring cereals

“…Soil analysis were made Mäkitie 1955, Kurki et ai. 1965) including boron determination (Hatcher and Wilcox 1950) by extraction with boiling water (Berger and Truog 1939) boron varied from 0.9 to 2.8 kg/ha B, and in 91 % of the cases the amount was 1.4 or less. The boron was mixed in the soil during seed bed preparation.…”
