“…After the activation process, coconut shell charcoal has many cavities or pores. According to Kumrić's research, the morphology of coconut shell activated carbon samples showed particles in the diameter range of less than μm to 120 μm [28]. The particles have an irregular shape and sharp edges.…”

Batik is a characteristic Indonesian textile product. The color of batik is one component that affects the quality of batik. Various types of batik dyes, one of which is remazol dyes. Remazol dyes are synthetic dyes that have strong chemical bonds. This is what underlies the process of production of the household batik industry in the village of Purwosekar, District of Tajinan, Malang Regency, with remazol coloring will produce liquid waste that is difficult to be deciphered naturally. This study aims to provide a water treatment solution using the coconut shell activated carbon adsorption method with chemical activation and the ability to adsorb remazol dyes. Adsorption experiments were carried out in batches with a mesh size of 8 with coconut shell carbon activated with 1 M HCl solution for 24 hours. The absorption of remazol dyes by coconut shell activated charcoal is carried out with a stirring speed variation for 60 minutes and the mass of activated charcoal to find the optimum adsorption conditions. Stirring speed variations are 30 rpm, 60 rpm, and 90 rpm, resulting in the highest efficiency at a speed of 90 rpm. While the variations in mass are 200 grams and 300 grams, the highest efficiency is obtained with a mass of 300 grams. Thus, the efficiency of the coconut shell activated carbon is proportional to the stirring speed and mass of the coconut shell activated carbon used

“…For this reason, the European Union has placed five neonicotinoid insecticides, including ACP, on the Watch List, i.e., the list of potentially hazardous pollutants. 7 Due to the high applicability of ACP as a pesticide despite its reported hazards, there are several methods reported for its determination recently, such as : surface-enhanced Raman spectroscopy (SERS), [8][9][10][11][12] liquid chromatography/mass spectroscopy (LC/MS), [13][14][15][16][17] ultra-high performance liquid chromatography (U-HPLC), [18][19][20] (HPLC), [21][22][23][24][25] spectrophotometry, [26][27][28] and fluorometry. [29][30][31][32][33] MIP based method fabricated over silica-carbon dots by sol-gel polymerization was used for fluorescent detection of ACP.…”

Acetamiprid (ACP) is a systemic insecticide widely used as a replacement for organophosphorus compounds to control sucking-type insects on leafy vegetables, fruits, and tea trees. In this work, bulk polymerized molecularly imprinted polymer was developed using ACP as template, 4-Vinyl pyridine as monomer and ethylene glycol dimethyl acrylate (EGDMA) as cross-linker in the presence of acetone as porogen. After evaluation of five polymeric ratios according to their equilibrium rebinding assay, the MIP comprising 1:3:50 (template: monomer: cross-linker) was found to show the best binding capacity, and thus was chosen as a template recognition for carbon paste electrode in cooperation with multiwalled carbon nanotubes as a signal enhancer. The developed electrode was morphologically and electrochemically characterized and was found to show a linear response for differential pulse voltammetry of 1 × 10-12 – 5 × 10-6 M equivalent to 0.222 – 111.3 ×104 ng/L with limits of detection and quantification of 7.35 × 10-3 and 0.022 ng/L, respectively. The electrode was efficiently applied for ACP detection in its pure solutions, commercial insecticide and spiked apple, tomato, and watermelon samples with recoveries from 95.55 -101.66% indicating its efficiency for application in regulatory units for hazardous food contaminants.

“…ODS or C 18 , aminopropyl (-NH 2 ), and PSA (primary and secondary amine) are the most common sorbents used in SPE cartridges [ 154 , 155 ]. Since the development of SPE techniques, most have relied on nano-sorbents, including modified silica, graphene, magnetic nanoparticles, and polysaccharides [ 58 , 156 ]. Recently, the cationic co-polysaccharide chitosan (poly-β-(1 → 4)-2-amino-2-deoxy-D-glucose) and its derivatives became one of the most established and suitable sorbents in separation procedures [ 10 , 12 ].…”

Analytical processes involving sample preparation, separation, and quantifying analytes in complex mixtures are indispensable in modern-day analysis. Each step is crucial to enriching correct and informative results. Therefore, sample preparation is the critical factor that determines both the accuracy and the time consumption of a sample analysis process. Recently, several promising sample preparation approaches have been made available with environmentally friendly technologies with high performance. As a result of its many advantages, solid-phase extraction (SPE) is practiced in many different fields in addition to the traditional methods. The SPE is an alternative method to liquid–liquid extraction (LLE), which eliminates several disadvantages, including many organic solvents, a lengthy operation time and numerous steps, potential sources of error, and high costs. SPE advanced sorbent technology reorients with various functions depending on the structure of extraction sorbents, including reversed-phase, normal-phase, cation exchange, anion exchange, and mixed-mode. In addition, the commercial SPE systems are disposable. Still, with the continual developments, the restricted access materials (RAM) and molecular imprinted polymers (MIP) are fabricated to be active reusable extraction cartridges. This review will discuss all the theoretical and practical principles of the SPE techniques, focusing on packing materials, different forms, and performing factors in recent and future advances. The information about novel methodological and instrumental solutions in relation to different variants of SPE techniques, solid-phase microextraction (SPME), in-tube solid-phase microextraction (IT-SPME), and magnetic solid-phase extraction (MSPE) is presented. The integration of SPE with analytical chromatographic techniques such as LC and GC is also indicated. Furthermore, the applications of these techniques are discussed in detail along with their advantages in analyzing pharmaceuticals, biological samples, natural compounds, pesticides, and environmental pollutants, as well as foods and beverages.
