Determination of calcium, magnesium and aluminium in magmatic rocks after ultrasonic leaching by flame AAS
M. Hikmet Özkan; Mehmet Akçay (2002)A method of ultrasonic leaching has been developed for the destructive analysis of magmatic rock $samples^1$. This method was applied to determine three new elements, Ca, Mg and Al, in magmatic rock samples. The accuracy ... -
Determination of manganese and iron in magmatic rocks after ultrasonic leaching by flame AAS
M. Hikmet Özkan; Mehmet Akçay (2002)An alternative sample preparation method has been developed for destructive analysis of magmatic rock sample. The method simply included the crushing, HF treatment and 1% HCl leaching steps of the rock samples under ... -
The determination of some heavy metal cations by TLC/ photodensitometry
Şahin Savaşcı; Mehmet Akçay (1996)The samples having complex matrices were analyzed for some heavy metal cations by using a thin layer chromatography/photodensitometry (TLC/PD) system. The rock samples were dissolved by suitable methods. Nickel, Cobalt and ... -
Determination of trace amounts of iodide by an inhibition kinetic spectrophotometric method
In this study, the reaction between Co(III)-EDTA and hypophosphite ion, catalyzed by Pd(II), was chosen as the indicator reaction. The inhibition kinetics of this catalytic reaction were investigated in the presence of ... -
Irmak sedimentinde stronsiyum iyonu fraksiyonlarının ardışık özütleme tekniğiyle belirlenmesi
Adil Elik; Mehmet Akçay (1999)Bu çalışmada, üzerinde özel bir kuruluşa ait selestisit zenginleştirme tesisi bulunan ırmak sedimentinde stronsiyum iyonunun miktarı, hareketi ve bağlanma biçimlerinin ardışık özütleme tekniğiyle belirlenmesi amaçlanmıştır. ... -
Kinetic spectrophotometric determination of trace copper(II) ions by their catalytic effect on the reduction of brilliant cresyl blue by ascorbic acid
In the present study, a novel catalytic-kinetic spectrophotometric method was developed for the determination of trace amounts of copper. It is based on the catalytic effect of Cu(II) on the reduction of brilliant cresyl ... -
Sivas kenti' nde ağır metal kirliliğinin yerel ve zamansal değişimi
Adil Elik; Mehmet Akçay (2000)Sivas Kenti'nin antropojenik ağır metal kirliliği, 1992-1994 yılları yaz sezonunda, kentin karakteristik özelliklerine sahip yedi istasyonda yerel ve zamansal olarak izlenmiştir. Pinaceae Pinus Sylvertris L. ve Fabaceae ...
