“…A method detection limit of 0.003 µg g −1 based on ID calibration was obtained from three spiked blanks. High precisions, in the range 0.14 to 0.30% RSD, were achieved, superior to previously reported precisions of Mg in freshwater 5,1012,14–16,25,26 . The above results confirm that the proposed method is suitable for the determination of Mg in the candidate drinking water CRM AQUA-1.…”

“…Evidently, the use of Sc internal standard significantly improves measurement precision and accuracy. High precisions of 0.055% to 0.66% RSDs for all three analytes in three CRMs using the combined standard addition calibration with Sc internal standardization were obtained, superior to those reported in previous studies 5,1012,14–16,24,25 and comparable to values reported in NIST 1640a. About 3–33 fold improvements in precisions (3-fold for K and 33- for Na) were obtained using the combined standard addition calibration with Sc internal standardization, compared to measurement precisions obtained by using standard addition calibration alone.…”

“…To date, several elegant methods have been established for monitoring Ca 2+ in biological environments, including electrochemical strategies [11,12], atomic absorption spectrometry [13], fluorescence chemosensors [14], inductively coupled plasma atomic emission spectrometry (ICP-AES) [15], and so on. Among these methods, the photoelectrochemical (PEC) detection shows noteworthy advantages in sensitivity and simplicity with several unique features [16][17][18][19][20].…”

“…Para comprender los procesos ambientales de contaminación es fundamental analizar materiales de diferentes orígenes tales como agua, suelo, sedimentos, rocas, etc. Como parte de ello se requiere la determinación elemental de los componentes traza, menores y mayores de dichas matrices (Gómez-Nieto et al 2015). El monitoreo de elementos potencialmente tóxicos (EPT) es fundamental (Balasubramanian y Pugalenthi 1999), ya que los metales pesados y el arsénico son de los principales contaminantes del medio ambiente (Sastre et al 2002).…”

“…Sin embargo, debido a que las concentraciones de los EPT en minerales y residuos pueden ser de varios cientos de partes por millón (Singh y Agrawal 2012, Gao et al 2013, es común utilizar la flama como fuente de atomización (Skoog et al 2001). La EAA presenta intervalos lineales de concentración restringidos y sólo es posible la determinación monoelemental secuencial y no, como en otras técnicas, la determinación simultánea, lo cual dificulta su universalidad (Harris 2013, Gómez-Nieto et al 2015. Para realizar el análisis de una muestra es necesario que ésta se encuentre en forma líquida y libre de sólidos, por lo que es inevitable una preparación que involucre desde la digestión ácida de la muestra, asistida por microondas, hasta el paso de filtración a través de una membrana, con tiempos de preparación relativamente cortos (1 h).…”
