Prior to use, the PTFE membrane was soaked in 1.5% w/v ionophores chloroform solution for 24 hours. The effect of pH and concentration of KNO3 as ionic strength adjuster on the performance of electrode is reported in this paper. The pH of the solution was adjusted in the ranges of 1 to 10 using HCl and NaOH solution, while KNO3 concentration was varied in the range of 10-4 to 10-1 M. The best electrode performance was obtained at pH 5 with KNO3 concentration of 10-2 M. At this condition the electrode had sensitivity of (18.5 ± 0.2) mV/decade with response time less than 25 seconds.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]1-phenyl-3-methyl-5-pyrazolone,Chloroform solutions,Electrode performance,H2SbBP,Influence of pH,NaOH solutions,Polytetrafluoroethylene (PTFE),Selective electrodes[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]H2SbBP,Ion selective electrode,Neodymium[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.4028/www.scientific.net/KEM.811.153[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
